Product Description

HOT WORK TOOL STEEL**-AISI H*1, DIN1.***3, JIS SKD6, GB 4Cr5MoSiV

 

H*1 Hot Work Tool Steel is a 5% chromium hot work steel that is characterized by excellent impact toughness.

> It contains less vanadium than the widely-used H*3 hot work tool steel. This provides for the higher toughness, with some reduction in wear resistance and temper resistance.

> H*1 hot work tool steel is a deep-hardening, air-hardening steel that exhibits minimal size change during heat treatment.

> It has good resistance to thermal fatigue cracking (heat checking) and excellent resistance to gross cracking and thermal shock when water cooled in service. 

Heat Treatment:

Forge: at ***0℃****5℃ Cool slowly and anneal then.

Annealing: at **3℃***8℃ Cool slowly in furnace

Stress Relieving: heat slowly to ******6℃, and then cool in still air.

Hardening: Preheat to **5℃ and then heat to ***0℃ and hold for *5 to *0 minutes. Air cool (air quench)

APPLICATIONS: H*1 hot work tool steel is recommended for hot tooling applications where maximum resistance to cracking is required. Such applications include hot punches, die casting dies, forging dies, hot shear blades, hot gripper dies, and extrusion tooling.
