high speed tool steel


hss tool steel bar



ASTM A600 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.


HSS M35 is a conventionally manufactured cobalt alloyed high-speed steel. The various stages of the manufacturing process are chosen and controlled so that an end product is obtained with a good
structure in terms of carbide size and distribution. this is a distinct advantage for the finished tool.




AISI HSS M35 tool steel is usually used in conditions with the demand for high hardness . M35 steel is suitable 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.

Forging of ASTM A600 High Speed Tool Steel M35


Pre heat the AISI M35 high speed steel slowly and uniformly to 450-500°C and equalise. Then increase M35 tool steel more quickly to the forging temperature of 950-1100°C and equalise prior to forging. Do not allow the forging temperature to drop below 950°C, if this occurs re heating will be necessary. Always cool the steel very slowly after forging.


Heat Treatment of AISI 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.


Machinability of AISI M35 Tool Steel


High Speed tool steel M35 can be worked in the same way as other high-speed steels by plastic forming, machining, grinding, electrical discharge machining, welding and polishing. M35 tool steel is amenable to cold forming. In grinding, local heating of the surface, which might alter the temper, must be avoided. Grinding wheel makers can furnish advice on the choice of grinding wheels. Machining is carried out using carbide or high-speed steel tools.
