440C/S44004 high-carbon high-chromium steel is a martensiticstainless steel and 440B/S44003 in 440A/S44002 steel based on theaddition of carbon C and Mo Mo steel were developed, it is more440A/S44002 steel and 440B/S44003 steel has higher hardness, wearresistance, high heat resistance, and corrosion resistancetempering, 440C/S44004 steel still better high temperaturedimensional stability. 440C/S44004 ledeburite steel is steel, easyto form uneven carbide segregation to affect part life, so must becontrolled in the thermal processing process, and select theappropriate processing ratio.
