H13 chemical composition

Chemical composition (wt%):
C: 0.32 ~ 0.45,
Si: 0.80 ~ 1.90,
Mn: 0.20 ~ 0.50,
Cr: 4.75 ~ 5.50,
Mo: 1.10 ~ 1.75,
V: 0.80 ~ 1.20,
p ≤ 0.030,
S ≤ 0.030;
Heat treatment: (Delivery status: the Brinell hardness HBW10/3000 (≤ 235)), quenched: 790 degrees + -15 degree preheated, 1000

(Salt bath) or 1010 degrees (oven controlled atmosphere) + -6 degrees heating, air-cooled heat 5 ~ 15min 550 + -6 degrees tempering; annealing, heat

Processing;
Characteristics and Uses: The Department of the introduction of the U.S. H13 empty Hardened hot work die steel. The basic phase of its performance, purposes and 4Cr5MoSiV of steel

The same, but because of its high vanadium content, it is better performance than 4Cr5MoSiV steel temperature (600 degrees), hot work die steel use is

A representative steel.
