1.2581steel it is a typical high-heat-strength hot-work die steel, the alloy element W is the main component, and the mass fraction of W is as high as 8% or more.
Die-casting molds that require high load-bearing capacity, high thermal strength and high tempering resistance This type of steel is often used in molds. The steel contains more Cr and W elements that are easy to form carbides, so it has better hardness and strength at high temperatures, but its toughness and plasticity are poor.
The steel has good harden-ability and steel It can be hardened when the cross section is below 80mm.
1.2581 steel has a higher temperature change temperature, and its resistance to alternating cold and heat is good.
However, these high-temperature properties are related to the quenching temperature and increase with the increase of the quenching temperature.
Characteristics and scope of application:
hot work die steel, which is a commonly used die-casting die steel. Low carbon content, high toughness and good thermal conductivity; at the same time, it contains more carbides to form elements chromium, tungsten, vanadium, phase transition temperature...
1.2581 hot work die steel is commonly used die casting die steel.
Low carbon content, high toughness and good thermal conductivity; at the same time, it contains more carbides to form elements chromium, tungsten, and vanadium. The phase transition temperature is increased, so that the steel has high high temperature strength, hardness and good heat resistance. Fatigue; hardenability.
Mechanical properties:
l Hardness: Annealed, 255～207HB, indentation diameter 3.8～4.2mm
l Heat treatment specification and metallographic structure: Heat treatment specification: quenching, 1075～1125℃ oil cooling.
l Delivery status: Brinell hardness HBW10/3000 (≤255~207)
