AISI T4 tool steel is one of tungsten type high speed tool steel, which belongs to ASTM A600. Other equivalent steel are DIN 1.3255 / S 18-1-2-5, JIS SKH3.
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.
