Mold steel SKD11 the highest heat treatment hardness is how much

Mold steel material SKD11 maximum heat treatment hardness is 255HBS.


SKD11 is a high wear-resistant toughness common cold-work die steel, high-carbon high-chromium alloy tool steel and vacuum degassing refining steel, pure steel, with good hardenability, quenching deformation of a small amount of good hardenability. The steel by the ball annealing softening treatment, good workability, small and uniform carbide particles, without having to worry about strengthening the quenching and tearing cracking elements molybdenum, vanadium added to the special.

Its chemical composition is:

Si silicon ≤ 0.40

Mn manganese ≤0.60

P Phosphorus ≤0.030

S sulfur ≤ 0.030

Cr chromium 11.0-13.0

Mo molybdenum 0.80-1.20

Ni nickel ≤0.50

V vanadium 0.20-0.50

Cu copper ≤ 0.25.
