GB/T 14667.1-1993

This standard specifies the technical requirements, test methods, and inspection rules for powder metallurgy iron-based structural materials, including sintering iron, sintering carbon-steel, sintering copper-steel, and sintering copper-molybdenum-steel. It is applied in the manufacturing of mechanical components such as gears, bearings, and structural parts produced through powder metallurgy processes, ensuring material consistency and performance in automotive, machinery, and industrial equipment applications. The standard is used for quality control and material selection in production and procurement contexts within the powder metallurgy industry.
