What are the differences in hardness, wear resistance and cost between materials commonly used in Roller processing parts?

Materials commonly used for Roller processing parts vary significantly in hardness, wear resistance and cost. Here's a detailed breakdown of these differences:
1. Hardness difference:
Metals: such as cast iron, steel and stainless steel, have higher hardness. For example, stainless steel typically has a higher hardness, which allows it to last longer in high-stress and high-wear environments.
Plastics: such as nylon, polyurethane, etc., have relatively low hardness but good elasticity. Among them, nylon material maintains a certain degree of hardness and also has certain wear resistance.
Special materials: such as UPE (ultra-high molecular weight polyethylene), whose hardness index is usually between 60-70 and has good wear resistance and durability.
2. Differences in wear resistance:
Metals: such as cast iron and steel, which exhibit excellent wear resistance due to their high hardness and strength. Stainless steel also has good wear resistance in certain environments due to its corrosion resistance.
Plastics: Materials such as nylon and polyurethane have good wear resistance and are especially suitable for occasions that require frequent rolling and friction.
Special materials: UPE materials are widely used in Roller processing parts that require high wear resistance due to their excellent wear resistance.
3. Cost difference:
Metal: Although metal materials have high hardness and wear resistance, their costs are also relatively high. Stainless steel is generally more expensive than regular steel and cast iron.
Plastic: The cost of plastic materials is relatively low, especially materials such as nylon and polyurethane. Their good wear resistance and moderate hardness make them common materials for Roller processing parts.
Special materials: Special materials such as UPE may cost more than ordinary plastic materials, but due to their excellent wear resistance and durability, they are still cost-effective in some specific applications.
To sum up, the material selection of Roller processing parts needs to be weighed according to the specific application environment and needs.
