GB/T 32247-2015
ActiveFerritic ductile iron castings suitable for low temperature service
低温铁素体球墨铸铁件
Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and marking for ferritic ductile iron castings intended for low-temperature service. It is applied in industries such as wind power, rail transit, and heavy machinery, where components like gearbox housings, hubs, and brackets must maintain impact toughness and structural integrity at temperatures as low as -40°C. The standard ensures reliable performance in cold climates or cryogenic environments, guiding both manufacturing and quality acceptance.
