GB/T 3098.8-2010
ActiveMechanical properties of fasteners - Parts for bolted connections for use at temperatures from -200℃～+700℃
紧固件机械性能 -200℃～+700℃使用的螺栓连接零件
Application Summary AI generated
This standard specifies the mechanical property requirements for bolts, screws, and studs used in bolted connections exposed to extreme temperatures ranging from -200°C to +700°C. It is applied in industries such as aerospace, petrochemical, and cryogenic engineering, where fasteners must maintain strength and reliability under severe thermal conditions. The standard ensures that materials and heat treatments are selected to prevent brittle fracture at low temperatures and creep or relaxation at high temperatures.
