NICKEL ALLOY AL6XN BUTT WELD FITTING ASTM B366 NO8367 ELBOW 90DEG LR
概述
- AL6XN is a superaustenitic stainless steel with outstanding resistance to chloride pitting， crevice corrosion and stress corrosion cracking. It is a low carbon， high purity， nitrogen-bearing"super-austenitic"stainless alloy. The AL-6XN alloy was designed to be a seawater resistant material and has since been demonstr ated to be resistant to a broad range of very corrosive environments. It is readily available from stock in a wide range of product forms， including thick plate that is suitable for multi-pass welding during field fabrication.
- The high strength and corrosion resistance of the AL-6XN alloy make it a better choice than the conventional duplex stainless steels and a cost effective alter native to more expensive nickel-base alloys in applications where excellent formability， weldability， strength and corrosion resistance are essential. It is also a cost-effective alternative to less expensive alloys， such as Type 316， that do not have the strength or corrosion resistance required to minimize life cycle costs in certain applications.
- 高含量的镍和钼提高了抗氯化物应力腐蚀开裂的能力。为了提高在海水中的性能，铜（Cu）被有意控制在残余水平40。AL-6XN 合金的合金成分较高，在氧化性氯化物溶液中抗缝隙腐蚀和点蚀的能力以前只有镍基合金和钛才能达到。
