5. 1.2344 die steel bar Shaping: Hot forged / Hot rolled
6. 1.2344 die steel bar Surface condition: Black surface/turning/milling/grinding/polishing
7. Annealing Hardness: HB230 Max
Hardness after Q+T(quenching+tempering):47-49HRC
8. Hardness&tempering relationship:
9. Properties: Under medium temperature conditions, it has good toughness, thermal fatigue and wear resistance. High thermal strength and hardness. Less thermal deformation and less oxide skin when air quenching, erosion against molten aluminum.
10. 1.2344 die steel bar Application:Widely used in making hot extrusion die , core rod, pressing forging die, forging hammer die and precision forging die. And also used verious felids.
