Description
High-speed tool steel The performance characteristics of high-speed tool steel with purpose
(1) use of steel DianZhaLu smelting, the silicon content not specified limit.
(2) in order to improve steel cutting machining, the buyer's request, can be provisions for sulfur ω (S) 0.60% ~ 0.15%.
(3) of residual elements in steel (mass fraction) : 0.30% or Ni; Cu 0.25% or less.
(4) is the high tungsten molybdenum content allowed ω (Mo) more than 1.00%. Steel tungsten molybdenum and the relationship is: when molybdenum content more than ω (Mo) 0.30%, tungsten content reduced correspondingly, in molybdenum content more than ω (Mo) 0.30% of the part, each ω (Mo) 1% can replace ω (W) 2%, if meet this kind of case, in this GangHao add after "Mo".
(5) W6Mo5Cr4V2 steel according to both the supply and the demand agreement, adjust the content of vanadium ω (V) 1.60% ~ 2.20%.
