Product Basic Information:
Smelting Method
Non-Vacuum Induction Furnace + LF + ESR
Feature
T4 is Tungsten series high speed steel, T4 tool steel is similar with T1 , but with 4.25~5.75% cobalt added, to increase heat resistance. The red hardness of T4 steel and the high temperature hardness is higher than 1.3355 tool steel. AISI T4 tool steel is a deep hardening alloy capable of Rockwell C 64 hardness. DLDT is a 1.3255 steel chinese main supplier , stockist and wholesalers.
