High-carbon Chromium Bearing Steel
[Translator Note. Text in red indicates the ?€?Amendment 1?€?]
1 Scope
This Standard specifies the order contents, dimension, shape, technical requirements, test methods, inspection rules, packaging, marking and quality certificate of the high-carbon chromium bearing steel.
This Standard is applicable to the hot-rolled or forged round-steels, wire-rods, cold-drawn (cold-rolled) round-steels (straight-strip or disc-shaped) and steel-pipes that are made of high-carbon chromium bearing steel and used for manufacturing bearing ring and rolling body. The continuously cast steel is not recommended to be adopted as the steel for manufacturing steel balls.
Based on the agreement by both the supplier and the purchaser, steels and steel-billets of other varieties and specifications may also be supplied; and the specific requirements shall be indicated in the contract.
