Does everyone know about the 42CrMo material?
Thread Content
Recently, the 42CrMo material has been increasingly used for pump shafts. I know that this material has a high hardness, but I would like to ask the experts whether it has a bainite structure What is its corrosion resistance like?
42CrMo is an alloy steel; its corrosion resistance is similar to that of ordinary steels, and it belongs to the category of materials with poor corrosion resistance
42CrMo is a quenched and tempered steel; after quenching and tempering, its main microstructural phase is 70% martensite, with the remainder being sorbite, and its corrosion resistance is average.
42CrMo has a high hardness, making it suitable for use in large gears; the pinions that pair with them can be made of 35CrMo. However, its corrosion resistance is that of ordinary steel – it is a non-corrosion-resistant alloy steel
