ASTM A462 Alloy Al6XN / UNS N08367 WN RF Mechanical Nickel Alloy Steel Flanges
ASTM A462 specifies high-performance alloy steel flanges, including the Al6XN alloy (UNS N08367). Al6XN is a super-austenitic stainless steel known for its excellent corrosion resistance, particularly in chloride-rich environments. These flanges are designed with a weld neck raised face (WN RF), ensuring a robust and leak-proof connection in various piping systems.
UNS N08367 also commonly referred to as alloy AL6XN® is a low carbon, high purity, nitrogen-bearing "super-austenitic" nickel-molybdenum alloy with excellent resistance to chloride pitting and crevice corrosion. Alloy AL6XN’s high strength and corrosion resistance makes it a better choice than the conventional duplex stainless steels and a cost effective alternative to more expensive nickel-base alloys where excellent formability, weldability, strength and corrosion resistance are essential.
Beneficial features, some of which include
- Excellent resistance to pitting and crevice corrosion in chloride solutions
- Practical immunity to stress corrosion cracking in NaCl environments
- High strength and toughness
- 50% stronger than stainless steel
- ASME coverage up to 800° F
- Easily welded
