W18Cr4V2Co8

Profile

This page is mainly introduced the W18Cr4V2Co8 chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of W18Cr4V2Co8,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.
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%.
