GB/T 6803-2008
AbolishedTest method for drop-weight test to determine nil-ductility transition temperature of ferritic steels
铁素体钢的无塑性转变温度落锤试验方法
Application Summary AI generated
This standard specifies the drop-weight test procedure for determining the nil-ductility transition temperature (NDTT) of ferritic steels. It is applied in the metallurgical industry and structural engineering to evaluate the brittle fracture resistance of steel plates, forgings, and welds used in pressure vessels, bridges, and pipelines, particularly for low-temperature service conditions. The test is critical for quality control and material selection in applications where sudden, catastrophic fracture must be avoided.
