High temperature Metal Mesh Belt Materials

The strength of a metal belt changes with change in temperature: this fact is always considered while choosing the metal for a specific application. Although strength factors are only a part of the process, while choosing materials for the belts, several other factors are also taken into consideration such as atmosphere, temperature limit and heating effect on the surface of the mesh belt.The following instructions should be taken into account while choosing a material in combination with the strength factors table for the use with weave, double weave and compound weave belts.

The welded Nichrome wire mesh belts are produced in a regular fabric by inserting a connector into each spiral pair. The applicable belt types are: Balanced (B), Double balanced (DB), Cleartrac (CTB) and Compound balanced (CB).

Adjustments

1. If the connector gauge is double or higher gauges heavier than the spiral gauge, then the consecutive larger wire size is used to find the maximum permissible tension.

2.Permissible tension at the high temperatures = lbs/foot max allowable tension at room temperature/strength factor.

3. The following diagram shows a single belt. For compound balanced CB belts, the chart value is multiplied by the count of elemental belts, a number immediately following CB in the mesh designation.

 1. In the carbon precipitation limit, a higher grade of stainless steel 316 or 347 specifically in ornate class Lehr applications is considered.

2. For Lehr applications the mesh belt is predominately 2% chrome carbon steel, although at temperatures lower than oF, it would be costly to use high carbon steel.

3. 3% chrome is sensitive to oxidation at this temperature limit

4.   Inconel alloy in nitrogen containing conditions at temperatures more than oF can be used as it is less sensitive to nitrogen embrittlement.

5.  For infrared food processing applications, stainless steel 316 is used for temperature conditions up to oF. Steel 304 is not an optimal choice for this operation limit.

6.  Steel 316 oxidizes at temperatures more than oF.

Instructions for choosing wire analysis for metal mesh belts Material Temp  oF Description and application Plain steel low carbon C 600 Dry conditions for light and moderated stress, where no rigorous wear tends to occur, and in low temperature ovens Galvanized carbon steel C C 350 For damp or slightly corrosive conditions and caustic washing application, furnished in low carbon for moderate stresses ad in high carbon for large stresses High carbon C C Dry conditions for large weights, where rigorous wear may occur, and in moderate temperature furnaces. For example glass annealing and metal tempering bluing alloy Mayari R These alloys have different chemical composition, have features better than high carbon steel for Lehr belt operations in the glass annealing temperature limit 3% chrome For temperatures more than oF about oF, with considerably higher oxidation resistance, surface and configuration stability than 1% chrome steel and increased strength 17 % chrome T430 For corrosion resistance in the natural, fresh water, steam, food, dairy products, nitric acid and other oxidizing conditions. The steel 430 offers higher corrosion resistance than that of grade 410 and it doesn?ˉt embrittle quickly. However it offers resistance to gradual scaling at temperatures about oF, it is not often utilized in the elevated temperature conditions excluding for sulfur gases as it vigorously losses strength at temperatures more than oF 18-8 T304 Steel grade 304 has excellent corrosion resistance, particularly in the sea water and commercial conditions, polluted water, elevated temperature steam, food, dairy products, organic compounds and non-oxidizing conditions, however it offers resistance to gradual scaling up to oF, it is not widely utilized in the elevated temperature conditions as it is keen to carbide precipitation and embrittlement in the 800oF to oF temperature limit. For 800oF to oF temperature limit properties are similar to 347. 18-12 Mo T316 The inclusion of molybdenum to the basic 18 ¨C 8 analysis offers higher resistance to the identical chemical compounds that are partially corrosive to stainless steel 304. The steel grade 316 is specifically effective in corrosion resistance in sulfuric acid compounds. It also offers resistance to pitting corrosion that takes place in 18-8 kind with acetic and phosphoric acids, chlorides, bromides and iodides. Muriatic or hydrochloric acids will cause corrosion of steel 316 and steel 304. Nitric acid, although will cause corrosion of steel 316 more easily than steel grade 304. For the elevated temperature applications, the steel 347 is recommended. 25-20 Si steel 314 The steel grade 314 is widely utilized in the elevated temperature metal mesh belt applications about oF due to its high strength, outstanding resistance to oxidation and affordability. The steel 314 is commonly utilized in the copper brazing processes and for sintering of powdered metals. It contains high silicon content that significantly increases its resistance to oxidation and carburization. Due to high concentration of carbon present in this alloy, when it is used in the long periods for 800of to oF, this steel is subjected to carbide precipitation at the grain boundaries resulting feasible embrittlement and intergranular corrosion. The carbides when produced are readily re-dissolved by causing the mesh belt temperature above oF, keeping this temperature for minimum one hour, then a quick air cooling. 35-19 In the oxidizing conditions lower to oF, and under cyclic heating conditions, alloy 35-19 is recommended than steel 314. Alloy 35-19 produces a layer that is more reliable to the underneath metal than in conditions for steel 314, it also offers greater potential, lower extension and less carbide embrittlement as compare to steel 314. The alloy 35Ni-19 Cr has high resistance to thermal shock. 35-19 Cb The alloy is equivalent to 35Ni-19Cr with inclusion of columbium that prevents the carbide precipitation. Moreover its also higher silicon concentration as compare to alloy 35-19 that enhances the resistance to oxidation and carburization. Preferred when there is prolonged exposure in the temperature limits of oF to oF limit and where the highest temperature does not increase more than oF. It offers high oxidation resistance to carburizing and carbonitriding conditions at temperatures about oF Inconel alloy 600 The superalloy Inconel has significant chemical compositions. Analyses show its higher scaling resistance in the cyclic heating operations in the oxidizing conditions than the earlier Inconel test. In the sulfur free conditions, this alloy can be used at temperatures about oF. In the sulphurous conditions, its applications are limited to oF for oxidizing and oF for reduction applications.

Inconel alloy 600 offers greater strength as compare to steel grades 314 and 35-19 at temperatures more than oF. It has outstanding resistance to intragranular corrosion at the elevated temperatures and its resistance to hydrogen, ammonia and nitrogen enables to be used in the nitriding conditions. Inconel alloy offers outstanding resistance to molten aluminum brazing flux.

 

Instructions for wire analysis for metal mesh belts Material Max temp, of Description and uses Inconel alloy 604 This new alloy is primarily a columbium stabilized kind of standard Inconel alloy, no brittlness and ductility loss due to carbide precipitation. Containing 78% nickel, extremely higher than 40% minimum content needed for avoiding sigma phase production, therefore it will not embrittle. Inconel alloy is specifically suitable in the carburizing conditions and installations where the mesh belt is subjected to interchange nominally reducing and oxidizing conditions. 80-20 Cb The high nickel alloy has been widely utilized for several years offering prolong Instructions for wire analysis for metal mesh belt life at the high temperatures. 80-20 Cb has outstanding oxidation resistance and high mechanical strength features for the preferred application temperature limits. The inclusion of columbium as a stabilizing element provides this alloy resistance to the green rot mechanism that may take place in the temperature limit of oF to oF. Hastelloy alloy X Outstanding strength and oxidation resistance about oF is a feature of Hastelloy alloy X. It produces a extremely reliable oxide layer that doesnt spall at the elevated temperature. It also offers outstanding resistance to the reducing and neutral conditions. High price is the only exception on its use for Instructions for choosing wire analysis for metal mesh belt applications. Nichrome 70/30 alloy This nichrome alloy contains 70% nickel and 30% chromium offering high oxidation resistance in the oxidizing and exothermic conditions at temperatures in abundance of oF.

 

It is to be noticed that the strength is the sole factor that is considered inthe selection of metal mesh belts for the elevated temperature application. The strength values stated by different consistent lab researches show significant change in analyses of metal mesh belt  applications in the field, under presumably identical conditions, often provide a broad variation in the useful life.

Allowances are made for commercial variations in the chemical composition and mechanical characteristics of wire, various kinds of mesh formation, types of corrosion, effect of atmosphere, time at the critical temperature, thermal shock, mechanical stress, non- uniform loading, pulley sizes, and different other conditions

Choosing the right polyester mesh beltpolyester mesh belt for printing can have a significant impact on the quality and efficiency of the printing process. Here are four key pieces of advice to help you make the best decision:

1. Consider the mesh count: The mesh count of a polyester mesh belt refers to the number of threads per inch. A higher mesh count typically allows for finer detail and higher resolution printing, while a lower mesh count is better suited for heavier ink deposits and rougher surfaces. Before choosing a mesh count, consider the level of detail in your designs and the type of materials you will be printing on.

2. Evaluate the material: Polyester mesh belts can be made from a variety of materials, each with its own unique properties. For example, monofilament polyester belts are known for their durability and solvent resistance, making them ideal for long print runs and harsh printing environments. On the other hand, multifilament polyester belts are softer and more flexible, making them better suited for delicate fabrics and intricate designs. Consider the specific requirements of your printing application to choose the most suitable material.

3. Check the tension and tracking system: Proper tension and tracking of a polyester mesh belt is essential for achieving accurate and consistent printing results. Make sure to choose a belt with a reliable tensioning system that allows for easy adjustments and maintenance. Additionally, opt for a belt with a tracking system that ensures the belt stays properly aligned throughout the printing process, minimizing the risk of misregistration and print defects.

4. Look for heat resistance: If you will be using your polyester mesh belt for heat curing processes, such as in textile printing or curing UV inks, it is important to choose a belt that can withstand high temperatures without losing its shape or tension. Look for belts made from heat-resistant materials and ensure they are properly heat-treated to ensure their longevity and performance under high-temperature conditions.

By following these four pieces of advice, you can make an informed decision when choosing a polyester mesh belt for printing. Taking into account factors such as mesh count, material, tension and tracking systems, and heat resistance will help you select a belt that meets your specific printing needs and ensures high-quality results. Investing in the right polyester mesh belt can ultimately improve the efficiency, accuracy, and reliability of your printing process, leading to better overall printing outcomes.
