Comparison of high chrome cast iron and high chrome cast steel

High chromium cast iron and high chromium cast steel are not the same material, and there are obvious differences in their composition, performance characteristics, and applicable occasions.
1. Concept introduction
High chrome cast iron and high chrome cast steel are two different casting materials. High chromium cast iron is a cast iron material containing high chromium alloy, with high wear resistance, high strength and corrosion resistance. And high chromium cast steel is a kind of steel casting material containing high chromium alloy, in addition to high wear resistance, high strength, corrosion resistance and other characteristics, but also has good toughness and soldability.
2. constituent
The main components of high chromium cast iron and high chromium cast steel are cast ferrite, but they have different chromium content. The chromium content of high chromium cast iron is usually between 12% and 30%, while the chromium content of high chromium cast steel is generally between 1% and 5%. In addition, high-chromium cast steel may also contain other components, such as nickel, molybdenum, vanadium, etc.
3. Performance characteristics
High chromium cast iron has the characteristics of high hardness, high wear resistance and good corrosion resistance, which is suitable for manufacturing wear resistant parts, corrosion resistant parts and other workparts. High chromium cast steel not only has high wear resistance and corrosion resistance, but also has good toughness, suitable for the manufacture of high strength and high wear resistance of mechanical parts, such as forklift teeth, grinding plate, etc.
4. Applicable occasion
Because the high chrome cast iron and high chrome cast steel have different performance characteristics, they also have differences in the applicable occasions. Generally, high chrome cast iron is suitable for severe wear, such as coal mill, ball mill, cement machine, and high chrome cast steel is suitable for vibration or impact, such as high-speed trains, large bearings, etc.
