High Toughness A2 Steel Spot Purchase Supply - China

The hardness of A2 is higher than SKD11 after heat treatment.

After tempering at high temperature (500-520℃), it can reach a high hardness of 60-62HRC, surpassing SKD11 in terms of strength.

A2 is an American high-toughness and wear-resistant tool steel, which is an air-hardened steel.

The mass fraction of carbon in this steel is about 1%.

After heat treatment, the hardness can reach 57~62HRC.

The mass fraction of chromium is about 5%.

After polishing, the steel surface has a darker gloss, excellent corrosion resistance, and extremely strong ductility.

The mold cutting edge has good damage resistance.

The steel has good hardenability, uniform carbide distribution, certain impact resistance and good wear resistance.

It has good air quenching performance, small dimensional deformation after air quenching, uniform and fine carbides, and good wear resistance.

Useful features:

(1) Good machinability and grindability.

The machinability and grindability are both better than SKD11, so the service life of processing tools is longer and the number of processing man-hours is saved.

(2) Advantages in heat treatment: The quenching hardening energy is higher than that of SKD11, so it can improve the defect of insufficient hardness during vacuum heat treatment.

(3) Advantages in wire cutting processing: High-temperature tempering can reduce residual stress and eliminate residual Waston iron, which can prevent cracks and deformation caused by wire cutting processing.

(4) Advantages of surface hardening treatment: The surface hardness after surface hardening treatment is higher than that of SKD11, so the mold performance can be improved.

(5) Advantages in repair welding operations Since the preheating and post-heating temperatures are lower than those of SKD11, the repair welding operations are easier.

Features: General cold work die steel, high hardness, high toughness.
