People also askWhich is better 42crmo4 or 42crmo4?Which is better 42crmo4 or 42crmo4?BS EN 42CrMo4 round steel has better performance than 34CrMo4 steel due to the carbon and chromium content is higher.42CrMo4 alloy steel has higher strength and hardenability.The 42CrMo4 alloy material also has high fatigue strength and good low-temperature impact toughness.The temper brittleness is not obvious.42CrMo4 Alloy Steel,BS EN 10250 Engineering SteelMaterials of Engineering - MAFIADOC.COM

Tempering relieves the internal stresses in the hardened steel in part by precipitating various carbides of iron at fairly low temperature,which coarsen as the tempering temperature is increased.The increasing particle separation results in a loss of hardness and strength accompanied by increased ductility.Machining of Hard Materials - PDF Free DownloadFigure 30 shows the tool life for four different steels (50 CrMn4 heat treatable steel,16 MnCr5 case hardened steel,and 90 MnV8 and X210 Cr WI2 tool steels) all heat treated to the same hardness
