B30镍白铜 预硬铜材 B30化学成分 B30 copper is microalloy not weeken the pre hardened plastic die steel and bayesian shape steel. The alloy Shanghai long into the development of innovative patent products, B is baosteel company code. Nitriding process can be further strengthened, and its performance is better than that of the same type of 718 Swedish steel (ASSAB). The steel welding heat affected zone hardness change significantly smaller than 2738 steel, welding performance is better. On this basis, get a uniform hardness distribution of welding materials is structural steel welding rod J107Cr, corresponding welding process is 350 ° C preheating, welding 350 ° C and 350 ° C tempering after welding B30镍白铜化学成分: 镍 钴 Ni Co:29.0-33.0 铁 Fe:0.9 锰 Mn:1.2 硅 Si:0.15 铅 Pb:0.001 硫 S:0.01 碳 C:0.05 磷 P:0.006 铜 Cu:余量 力学性能:抗拉强度 σb (MPa):(热轧)390~540; (冷拉)钢材厚度或直径 8~20时:530~755; >20~30时:510~735; >30时:490~685伸长率 δ5 (%):(热轧) ≥22;(冷轧) ≥7.0断面收缩率 ψ (%):(热轧) ≥36硬度 :(热轧) ≤170HB;(冷拉钢)152~217HB
