镍白铜加工B30化学成分#镍铜合金B30
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铜材是微合金非调质预硬化塑料模具钢和贝氏体型钢。该合金上海隆进研制的创新型专利产品, B是宝钢的企业代号。可进行渗氮处理进一步强化, 其性能优于同类型的瑞典718钢 (ASSAB)。该钢焊接热影响区的硬度变化明显比2738 钢小, 焊接性能较好。在此基础上, 获得较均匀硬度分布的焊接材料是结构钢焊条J107Cr,相应的焊接工艺是 350°C 预热、 350°C 焊接及焊后 350°C 回火。
