Material Name: Alloy tool steel
Grade: x38crmov5-1
Standard: GB / T 1299-1985
● Features and application:
Impact-resistant tool steel, composition, a single higher quenching hardness and high temperature strength. Often used as wear resistance to withstand high impact loads but requires tools such as pneumatic tools, chisels and heavy-duty work performance molds, cold shear blades, pneumatic hammers and other tools.

Si Si: 0.50 ~ 0.80
Manganese Mn: ≤ 0.40
Sulfur S: ≤ 0.030
Phosphorus P: ≤ 0.030
Chromium Cr: 1.00 ~ 1.30
Ni: to allow the residual content of ≤ 0.25
Copper Cu: to allow the residual content of ≤ 0.30
Tungsten W: 2.00 ~ 2.70
● Mechanical Properties:
Hardness: Annealed, 285 ~ 229HB, indentation diameter of 3.6 ~ 4.0mm; quenching, ≥ 57HRC
● Heat treatment and microstructure specifications:
Standard heat treatment: quenching the sample 860 ~ 900 ℃, oil cooling.
● Delivery status: the status of delivery of steel to annealing.
