Scope

Main technical content: This standard specifies the ordering content, classification and code, dimensions, shape, weight and allowable deviations, technical requirements, test methods, inspection rules, packaging, marking, and quality certificates of hot-rolled steel bars for large-scale shafts. It sets strict requirements for the chemical composition and mechanical properties of high-quality carbon structural steel and alloy structural steel used for large-scale shafts, meeting the needs of mechanical large-scale shaft applications. This standard applies to hot-rolled high-quality carbon structural steel and alloy structural steel bars with diameters of 250mm to 380mm, which are mainly used for large-scale shafts in mechanical equipment.
