什么是哈氏合金管呢?

  说起哈氏合金管,相信很多人都见过,但是大部分人并不认识它,今天小编给大家介绍一下什么是哈氏合金管吧:

????  国际通称:哈氏合金、C-276、INCONEL Alloy C-276、HC-276、Hastelloy C-276、UNS N10276、W.-Nr. 2.4819、ATI C-276、Nicrofer 5716 hMoW-Alloy C-276、NAS NW276

  执行标准:ASTM B575/ASME SB-575、ASTM B574/ASME SB-574、ASTM B622/ASME SB-622、ASTM B619/ASME SB-619、ASTM B366/ASME SB-366、ASTM B564/ASME SB-564

  主要成分:碳(C)≤0.01,锰(Mn)≤1.00,镍(Ni)≥57,硅(Si)≤0.08磷(P)≤0.04,硫(S)≤0.03,铬(Cr)14.5~16.5,铁(Fe)4.0~7.0,钼(Mo)15.0~17.0,钨(W)3.0~4.5,钴(Co) ≤2.5

  物理性能:C-276密度:8.9g/cm3, 熔点:1325-1370 ℃,磁性:无

????  热处理:1150-1175℃之间保温1-2小时,快速空冷或水冷。

  机械性能:抗拉强度:σb≥690Mpa,屈服强度σb≥275Mpa:延伸率:δ≥40%,硬度≤100(HRB)
