Scope

Main technical content: At present, there are no national or industry standards for bainite steel used in railway frogs. The current TB/T 447-2004 "Technical Specifications for High Manganese Steel Frogs" and TB/T 3467-2016 "Alloy Steel Composite Frogs" are industry standards that take frogs as the standardized object, and cannot set requirements for steel used in railway frogs. This standard for bainite alloy flat steel used in railway frogs can fill the existing standard gap and meet the production needs of bainite alloy flat steel used in railway frogs. This standard specifies the ordering content, dimensions, appearance, weight and allowable deviations, technical requirements, test methods, inspection rules, packaging, marking, and quality certificates of bainite alloy flat steel used in railway frogs, and is applicable to the manufacture of bainite alloy flat steel with a width of 100mm~200mm and a thickness of 30mm~150mm used in railway frogs.
