Forging of ASTM T4 Tool Steel Materials

Forging of T4 steel can be carried out from 850 to 1120°C (1775 to 2100°F).

Preheat T4 steel material uniformly and slowly to 860-880°C.

Increase the forging temperature up to 1050-1120°C.

T4 hss tool steel should be cooled very slowly after forging.

 

AISI/ASTM T4 Tool Steel Heat Treatment and Properties

Hardening:

Harden T4 high speed tool steel from a temperature of 1260-1290oC followed by oil, air quenching or warm bath at 550oC. Hardness after quenching is 63-66 HRC.

Annealing:

T4 steel should be annealed after hot working. Increase the temperature of T4 high speed steel to 860°C(Max220°C per hour). Hold at the temperature and then cool slowly with the furnace. The annealed hardness achieved should be below HB255.

Tempering:

Tempering temperature: 2x 560-580oC. Hardness after tempering is 64-65 HRC.
