Product Description
X50CrMoW9-1-1/1.2631 Alloy Cold Work Tool Steel
1: 1.2631 Steel Introduction
1.2631 The main components of mold steel include chromium, tungsten, vanadium, molybdenum and other elements. These elements play different roles in the steel, such as chromium can improve the hardenability and corrosion resistance of the steel, tungsten can enhance the wear resistance and thermal fatigue resistance of the steel, vanadium can refine the grain size of the steel, improve the strength and toughness of the steel.1.2631 die steel has high hardness, high strength, high wear resistance, high corrosion resistance and other characteristics. The steel in the appropriate heat treatment, the surface hardness can reach HRC50 or more, with excellent resistance to wear and corrosion resistance, can withstand a long time of high-intensity use.

7: 1.2631 Steel Application
1.2631 die steel is widely used in the manufacture of molds in the plastic, rubber and metal industries. Due to its excellent wear resistance and thermal fatigue resistance, the steel is particularly suitable for the manufacture of molds that need to withstand high temperatures and complex stresses, such as die casting molds, injection molds, extrusion molds and so on. In addition, 1.2631 die steel can also be used in the manufacture of tools such as knives, gauges, and other tools, as well as mechanical parts that need to withstand high-intensity friction and high-temperature environments.
8: 1.2631 Steel Heat Treatment
Hot Working Treatment:
1.2631 The hot working specification of mold steel includes heating temperature, holding time and cooling method. Appropriate hot working specifications can ensure that the internal structure and organization of the steel is uniform, and improve its mechanical properties and processing performance. Specific hot working specifications should be operated according to the manufacturer's requirements.
Soft Annealing Specifications:
In order to soften 1.2631 die steel, it should be heated to 790℃-840℃ and kept for a certain time. Then it should be cooled by appropriate cooling method to obtain the best softening effect. The specific parameters of the softening and annealing specification should be operated according to the manufacturer's requirements.
Hardening And Tempering:
Quenching is a critical step in strengthening and hardening 1.2631 die steel. The steel is heated to 830°C-870°C, held for a period of time and then quenched in oil or air. Tempering is to adjust the hardness and toughness of the steel, usually immediately after quenching and tempering treatment, the temperature is 480 ℃ -540 ℃, keep a certain period of time after cooling to room temperature. Specific quenching and tempering specifications should be operated according to the manufacturer's requirements.
