Wear Behavior of a Low-Alloy (AISI-SAE) 4140 Steel After

Jan 01,2016·Probably this is due to the low wear when tempering at 400 ° C,at which the microstructure of the steel will return back the stables phases which are probably bainite and ferrite.This kind of microstructures is generally ductile which will increase the effect of external forces on the weight loss.2848 Sebhi Amar/ Materials Today What is temper embrittlement,and how can it be controlled The original toughness of a steel which has suffered temper embrittlement can be restored by heating to above 600°C,and then cooling rapidly to below 300°C.However,the best method of avoidance is to reduce the embrittling impurities through control of raw materials and steel production.What is the difference between high strength alloy steel Mar 23,2021·4140 (G41400) has high strength and toughness,good hardenability,no obvious temper brittleness,high fatigue limit and multiple impact resistance after quenching and tempering,and good low-temperature impact toughness.The steel is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness.
