According to the production process, stainless steel round steel can be divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled stainless steel round bars are 5.5-250 mm. Among them: small stainless steel round bars of 5.5-25 mm are mostly supplied in bundles of straight bars, which are often used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25 mm are mainly used for the manufacture of mechanical parts or seamless steel pipe billets. .
Delivery status: Generally, the delivery is in the heat treatment state, and the type of heat treatment is indicated in the contract; if it is not indicated, the delivery is in the non-heat treatment state.
