Q:According to Chinese production standards, what are the specifications, dimensions, weights and allowable deviations of stainless steel round bars?

Stainless steel round bars can be divided into hot rolled, forged and cold drawn according to the production process. According to Chinese standard GB/T 1220-2007, the specifications of hot rolled stainless steel round bars are 5.5mm-250mm, of which, 5.5mm-25mm small stainless steel round bars are mostly supplied in straight bundles and are often used to manufacture steel bars, bolts and various mechanical parts. Stainless steel round bars larger than 25mm are used to manufacture mechanical parts or as seamless steel billets. The weight of stainless steel round bars can be calculated based on their diameter and length. The specific formula is: weight (kg) = diameter (mm)^2 × length (m) × 0.00623. In addition, the permissible range of deviation regarding stainless steel round bars needs to be judged according to different diameter range standards. In general, the minimum value is not less than ±0.08 and the maximum value is not more than ±0.58.
