lso Certification Hot Rolled Alloy Steel 42crmo Alloy Steel Coil
42CrMo Steel Material is hiah strenath steelIt has great touahness.strenath and hardenability.After auenchina and temperina treatment. it will get better fatique limit and shock resistance ability.It usually is used without obvious temper embrittlement after the quenching and temperino treatment.And its low-temperature impact toughness is good.So 42CrMo steel material round bar or sheet was widely used in the big or medium
vpe plastic mold with certain strenathand touahnessThe properties of 42crMo are close to the 35CrMoBut the content of carbon and chromium are hiqher than 35CrMo, so the strength and hardenability are better than 35CrMo material.
Compare with the 35CrMo,42CrMo is a better option.Due to its great properties, people usually use 42CrMo steel round bar or plate to make the important fittings those with higher strength and bigger cross-section size than 35CrMo.Such as the shaft,gearconnection rod,spring, engine cylinder 1200-2000mm petroleum drill attachesand etc.
42CrMo Steel Material Chemical Composition:
