说明
TP347H(1Cr19Ni11Nb)是一种高碳含铌的铬镍奥氏体不锈钢,由于含有稳定元素 Nb,其耐晶间腐蚀性能和耐多硫酸晶间应力腐蚀性能良好,在酸、碱、盐等腐蚀性介质中,其耐腐蚀性能与含 Ti 的 18-8 奥氏体不锈钢相似。因此,它被广泛应用于锅炉、发电、石油、化工、合成纤维、食品、造纸等行业。由于 Nb 比 Ti 更不易燃烧,该钢还可用作铬镍奥氏体不锈钢的焊芯。与 316 系列相比,这种钢具有更高的高温强度和更好的抗高温氧化性能,因此经常被用作热强度钢。
The 347H seamless tube material is cold-drawn and therefore cannot be hardened by heat treatment. But it can be hardened by cold working. The material can also be easily welded.
