Smelting Process EAF+LF+VD 2) EAF+LF+VD+ESR

Shaping Hot forged / Hot rolled

Surface condition: Black surface/turning/milling/grinding/polishing

Annealing Hardness: HB229 Max

Properties: Under medium temperature conditions, it has good toughness, thermal strength, thermal fatigue and wear resistance. Less thermal deformation and less oxide skin when air quenching, erosion against molten aluminum.

Application: Widely used in making casting die, thermal extruding die for machining aluminum casting parts, tools for punching holes, core rod

Weight(kg): Round bar=0.00617*R*R*L Flat bar=0.00785*T*W*L

Characteristic

1)Better toughness than conventional H13 2)Fine grain size with high toughness 3)High Strength at elevated temperature.

Coefficient of Linear Thermal Expansion 10^-6℃^-1
