Conveyor Belts Material

Materials used for conveyor belts.



Material

The belts are made of various materials according to the purpose of their application. The most common materials are standard black steel, galvanized steel, various types of stainless steel, heat-resistant steel and acid-resistant steel.

The working temperature of metal belts ranges from -200°C to +1200°C.

 

1. Common Black Steel

The advantage of common black steel is a quite high tensile strength at normal temperatures together with a relatively low price. This material can be successfully used for belts that are not exposed to any humidity at operating temperatures up to approximately 350°C.

 

2. Galvanized Steel

Its properties are the same as those of common black steel and, on top of that, the galvanized wires can be exposed to certain amount of humidity.

 

3. Stainless Steel

Stainless steel is an alloy of iron and chromium or of iron, chromium and nickel. In the first case, the resulting alloy is resistant to corrosion caused by humidity. In the second, the steel is resistant to accids and temperatures up to approximately 700°C.

Most commonly used stainless steels are DIN 1.4301, 1.4401 and 1.4310.

 

4. Steel Resistant to High Temperatures

This material is also a stainless chromium-nickel steel which is, thanks to its chemical composition, able to resist temperatures from 600 °C to 1200 °C.

The most frequently used are alloys with 3-5% Cr content suitable for working temperatures around 600 - 700°C.  For higher temperatures, steels of DIN 1.4841, 1.4864, 1.4828, 1.4887, 2.4869 and others are used.
