H13 Steel HS H13-MOD Hot Work Die Steel

As modified improved high-thermal-strength hot-work die steel, HS H13-Mod of material h13 equivalent, optimizes the ratio of C and Cr alloy elements on the basis of traditional h13 esr, reduces the content of harmful elements such as P and S, so that h13 steel equivalent has good thermal stability and thermal fatigue resistance.

Chemical properties of HS H13-MOD
Steel Grade C Si Mn P S Cr Mo V
HS H13-Mod 0.30~0.40 1.20~1.60 0.30~0.50 ≤0.015 ≤0.003 3.50~4.50 0.80~1.20 0.80~1.00

Features of HS H13-MOD
High resistance of tempering softening properties (the using temperature can improve 50℃ comparing with H13 steel).

Excellent Thermal Stability: the moulding die manufacturing of the H12-MOD can be under long time preservation of 620℃, the hardness is always higher than that of H13, and still maintain above 35HRC.

High thermal fatigue resistance: better than that of H13 steel.

Performance curve of tempering and CCT curve (continuous cooling transformation).
