Product Brand: free-cutting steel

Detailed description:

Alloy tool steel: 4CrW2Si
Standard: GB / T 1299-2000

Features and application:
Shock-resistant tool steel, the steel in chrome on the basis of silicon joined the W, thus a certain hardenability and high temperature strength at the same time, in the tempered state may be given a higher toughness. Is mainly used for production of high-impact load operation tools such as pneumatic tools, chisel, composite blanking trimming die, dies, cold cut with scissors and other punch tools, as well as some small-scale hot die.

Chemical Composition:
C: 0.35 ~ 0.45
Si: 0.80 ~ 1.10
Mn: ≤ 0.40
S: ≤ 0.030
P: ≤ 0.030
Cr: 1.00 ~ 1.30
Ni: to allow the residual content of ≤ 0.25
Cu: to allow the residual content of ≤ 0.30
W: 2.00 ~ 2.50

Mechanical Properties:
Hardness: Annealing, 217 ~ 179HB, indentation diameter of 4.1 ~ 4.5mm; quenching, ≥ 53HRC

Heat treatment parameters and microstructure:
Heat treatment specifications: The specimen quenched 860 ~ 900 , oil-cooling.

Delivery status: Delivery of steel to annealing.
