What is 440C Stainless Steel ?
440C is a high carbon martensitic stainless steel that has slightly more carbon than 440A and 440B giving it the highest hardness of any martensitic stainless alloy. This grade has excellent wear resistance making it perfect as a bearing steel used as ball bearings and bearing races.
440 STAINLESS STEEL SPECIFICATIONS
440A Stainless Steel
440A is a high-carbon martensitic stainless steel, AOD melted for refined quality and consistency. It contains slightly less carbon than 440B and 440C
440C Stainless Steel
440C is the hardest and most wear-resistant grade in the 440 series due to its highest carbon content. It achieves excellent dimensional stability and superior bearing performance after hardening.
