AISI H12 / DIN EN X35CrWMoV5 1.2605/1.2606 Tool Steel Bar / Rod 20-1000 mm
INTRODUCTION
For hot works tool steels application, we could supply some common tool steels, like H10 steel, H11 steel and H13 steel, and we could also supply AISI H12 tool steel materials for your hot works applications.
AISI h12 tool steel is a 4.75~5.5% chromium, general-purpose hot work steel. H12 tool steel contains (0.2~0.5%) less vanadium than the widely-used H13 hot works tool steel (0.8~1.2%). ASTM/AISI H12 Steel is a deep-hardening, air-hardening steel that exhibits minimal size change during heat treatmnet. H12 tool steel material has good resistance to thermal fatique cracking (heat cracking) and excellent resistnce to gross cracking and thermal shock when water cooled in service. So, we could say H-12 tool steel mainly has the following characteristics:
APPLICATIONS

PROCESSING
Forging of AISI H12 Tool Steel
Hot forming temperature: 1100-850oC.
AISI H12 Tool Steel Heat Treatment
Annealing
Heating Steel H-12 slowly and uniformly to 845~900℃, furnace cooling to 540℃ at a rate 10~20℃/hr. Hardness HB 229 max
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating H12 steel to approx.650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening
Tempering
Tempering temperature: 520-700oC, hold at least 2 hours, air cooling and double tempering.
