【Abstract】 With studying the main properties and carbide distributing roles of hot work die steel H13A and comparing to the steel 3Cr2WSV,It has found that the mainproperties of H13A are better than that of 3Cr2WSV. The steel H13A with lower alloy content has higher strength,toughness and long service life.更多还原
