M35 tool steel 


 M35 cobalt high speed steel compared to the cheap and easy to process, through appropriate heat treatment, obtain high hardness (HRC67 ~ 70), high red hardness (625 ℃ 4 小时, HRC63 ~ 65) and high wear resistance, toughness and resistance to bending strength of not less than the normal high-speed steel, can be overcome and die edge cracking, etc. collapse early damage. M35 tool steel is the main feature Co general purpose cutting tools with tool steel, hardened degree is 1200-1240C. Mainly used in hobs, broaches, end mills. Standards compare with AISI-M2 JIS-SKH51 factory condition, the ball annealing <225 features and applications: This high-speed steel tungsten steel. Appropriate to create a strong cutting wear and impact resistance tools, advanced die, screw die, than to be resilient and complex shape tools, reamers, milling cutters, iron, red top. Forging temperature :1100-900 ℃ annealing temperature: heated to 800-850 ℃, stay 2-4 hours at this temperature, the furnace is allowed to gradually cool. Cooling medium: air-cooled, oil, grade (550-580 ℃)
