GB/T 28909-2012
ActiveExtra-high strength structural steel plates in the heat-treatment condition
超高强度结构用热处理钢板
Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and packaging for extra-high strength structural steel plates that have been heat-treated. It is applied in the manufacturing of critical load-bearing components in industries such as heavy machinery, bridges, high-rise buildings, and pressure vessels, where the steel must achieve yield strengths above 690 MPa through quenching and tempering processes. The standard ensures consistent mechanical properties and weldability for plates used in demanding structural applications requiring high strength and toughness.
