Heat resistant W403 equivalent die steel

Heat resistant W403 mould steel   Among the well-known mold steels, Austrian W403 is a hot-working die-casting mold steel and one of the commonly used mold steels. It has excellent characteristics such as high heat resistance, excellent all-round toughness and ductility, high resistance to thermal fatigue and wear resistance. Sichuan Chongxin Special Materials' independently innovative process technology produces die-casting mold steel MCH13A, which has similar characteristics to W403 and is widely used in die cast mold making. Both have high heat resistance and good corrosion resistance, and can resist the erosion of chemical substances such as acids and alkalis. At the same time, MCH13A also has the characteristics of high cleanliness, uniform organization, grain refinement, high impact toughness, and good isotropy. It is used in aluminum alloy die-casting for automobiles, motorcycles and various automotive accessories. Mold steel composition table: MCH13A adopts advanced…
