(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%.
