供求信息描述: | GH159钴基变形高温合金 GH159合金是在国外多相钴基高温合金(MP合金)的基础上发展起来的一种新型高强度多相钴基高温合金。它的主要特点是:利用冷变形首先在面心立方基体中诱发产生交叉网状分布的片状ε相来阻止位错的长程运动而产生强化,再经过时效处理析出弥散的Ni3X相补充强化。该合多金具有超高强度、良好的塑韧性和高的应力腐蚀抗力等综合性能,并且在650℃的高温下仍能保持其高强度的特性。该合金不仅可广泛用于航空发动机的高温紧固螺栓等零件,也可用于应力腐蚀环境下(如海洋大气环境)服役的飞机用超高强度紧固件。供应的主要品种是冷拉棒材。 GH159化学成分 C:≤0.04 Cr:18~20 Ni:余 Co:34~38 Mo:6~8 Fe:8~10 Ti:2.5~3.25 Al:0.1~0.3 Nb:0.25~0.75 B:41 A182-F53 Super Duplex UNS S32760 F55 ASTM A182 F-55 SA182 F55 DIN 1.4501 UNS 32760 SA213 T91/T-91, SA213 T22/T-22, SA213 T11/T-11, SA213 T5/T-5, SA213 T9/T-9 Seamless Tubes for Boiler, Superheater & Heat-Exchanger SA213 TP347H, SA213 TP321H, SA213 TP304H, SA213 TP304L, SA213 TP304, SA213 TP316H, SA213 TP316, SA213 TP316L, SA213 TP316Ti, SA213 TP317L Seamless Tubes for Boiler, Superheater & Heat-Exchanger ASME SA516 Grade-70 Pressure Vessel Plates for Low Temperature Service, ASME SA515 Grade-70 Pressure Vessel Plates for High Temperature Service, ASME SA516 Grade-60 Boiler Plates, ASME SA515 Grade-60 Boiler Plates, ASTM A516-60 Pressure Vessel Plates ASTM A515-60 Pressure Vessel Plates ASTM A515-70 Boiler Plates ASTM A516-70 Boiler Plates |
