• Quick Details

   

  1:T4 steel introduction

      AISI T4 tool steel is one of tungsten type high speed tool steel, which belongs to ASTM A600specification, the standard for high speed tool steel materials. 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.

  6. 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.

   

  7: Delivery condition

      For hot rolled bar, usually the delivery condition is hot rolled, annealed, Black surface.
      For cold drawn plate, usually the delivery condition is cold drawn, annealed, milled surface
      For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
