• Quick Details

   

  1:M35 steel introduction

      M35 steel is a medium-alloyed high speed tool steel. It is also known as HSSE or HSS-E which is similar to M2, but with 5% cobalt added, which makes better hot hardness and wear resistance. AISI /ASTM A600 M35 high speed steel is suitable for heat treatment up to 66 HRC, and also offers excellent cutting performance and offers excellent cutting performance. AISI high speed Tool Steel M35 is suitable for broaches, taps, milling, reamers, hobs, shapers cutters, saws ,etc.

  Application	M35 are used for cutting tools such as cutting tools including broaches, milling cutters, reamers, end mills and saw blades. It is also a good quality wear resistant HSS grade for cold work area. Steel M35 is also suitable for cold work applications, where exacting demands are imposed on wear resistance. The steel possesses an admirable combination of wear resistance and toughness and in these respects superior to the high alloyed cold work steels.

   

   

  6. Heat Treatment of AISI Tool Steel M35 High Speed Material
      Soft-annealing 850°C - 900°C / 1560°F - 1650°F, slow cooling 10°C / 18°F/h to 700°C / 1290°F, hardness max 260 Brinell.
      Stress relieving 600°C - 700°C / 1120°F - 1290°F, approx. 2 hours at temperature, slow cooling to 500°C / 930°F.
      Hardening with preheating in two steps 450°C - 500°C / 840°F - 930°F, 850°C - 900°C / 1560°F - 1650°F and austenitizing at 1050°C - 1220°C / 1920°F - 2230°F. Quenching to about 550°C / 1022°F then cool in air to hand warm
      Tempering at 560°C / 1040°F or higher 2 times for at least 1 hour at full temperature is recommended.

   

  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.

  2275° F for max. hardness and abrasion resistance.

  Quench

      For full hardness, oil quench to 150-200° F. Air quench to 150° F. When quenching in hot salt maintain the quench just above the Ms temperature. After equalizing withdraw parts from the hot salt and air cooled to 150° F.

  Temper

      Double temper is mandatory, three tempers are sometimes preferred. Soak for 2 hours per inch of thickness. Air cool to room temperature between tempers. The best tempering range for hardness, strength and toughness is 1000 to 1050° F.

   

  8: Delivery condition

      For hot forged  bar, usually the delivery condition is hot forged, annealed/QT, rough turned/Black surface.
      For hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
      For hot forged block, usually the delivery condition is hot forged, annealed/QT, milled surface/Black surface
      For hot rolled plate, usually the delivery condition is hot rolled, annealed/QT, black surface.
      For cold drawn bar, usually the delivery condition is cold drawn, annealed/QT, peeled/black surface
