Product Details

INTRODUCTION

AISI T4 tool steel is one of tungsten type high speed tool steel, which belongs to ASTM A600 specification, the standard for high speed tool steel materials.

ASTM T4 tool steel is similar to T1 Tool Steel materials, but with 4.25~5.75% cobalt added to increase heat resistance. The red hardness of T4 steel and the high temperature hardness is a little higher than T1 tool steel. AISI T4 tool steel is a deep hardening alloy capable of Rockwell C 64 hardness.

APPLICATIONS

AISI T4 high speed tool steels are widely used as cutting tools, broaches and cold extrusion punches, turning, planing and milling cutters for roughing work.

Typical applications are:

Drills,
Milling Cutters,
Thread Cutting Tools,
Knurling Tools,
Cold extrusion punches
Broaches etc.

PROCESSING

Forging of ASTM A600 High Speed Tool Steel T4

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.

Heat Treatment of AISI T4 High Speed Material

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.
