40Cr Steel Equivalent,Mechanical Properties Chemical

40Cr Alloy Steel.40Cr steel is a kind of Chinese GB standard alloy steel for engineering and machinery purpose,and one of the most widely used steel grades.For 40Cr material hardness,specifications and equivalent,please see the table below.After quenching and tempering treatment,40Cr steel has good comprehensive mechanical properties,low temperature impact toughness,low notch 4140 Alloy Steel 1.7225 SCM440 42CrMo4 - OTAI The hardness of the steel can be increased if it has lower tempering temperature.For example,tensile strength of 225 ksi cab be achieved by tempering at 316°C (600°F),and a tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F).Hardening AISI 4140 alloy steel can be hardened by cold working,or heating and quenching.42CrMo Steel Equivalent,Chemical Composition,Mechanical IntroductionApplicationsDatasheetEquivalent42CrMo steelis a Chinese alloy steel,and has high strength and toughness,good hardenability,and no obvious temper brittleness.After quenching and tempering treatment,it has high fatigue limit and resistance to multiple impacts,and good low temperature impact toughness.See more on theworldmaterial20CrMoTi Nitriding gear steel Shew-e steelSep 26,2019·Ordinary tempered structural steel like 42CrMo4,35CrMoV,25Cr2MoV and other materials can also be used to make nitriding gear.20CrMnTi gear steel is a commonly in accordance with the standards of the former Soviet union in China according to GB/T 3077,GB/T 5216-2014 and GB/T 33160-2016(gears for wind power generation).The table below showed
