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, reduces the content of harmful elements such as P and S, so that H13 equivalent has good thermal stability and thermal fatigue resistance.

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).
