NXF ASTM A240 316H /1Cr17Ni12Mo2/31609 DN15-1200 Class 150-2500 Stainless Steel 316H Socket Welding & Threaded Union

Alloy 316H (UNS S31609) is a high carbon modification of Alloy 316 developed for use in elevated temperature service. The alloyhas higher strength at elevated temperatures and is used for structural and pressure vessel applications at temperatures above932°F (500°C). The higher carbon content of 316H also delivers higher tensile and yield strength than 316/316L and its austeniticstructure provides excellent toughness down to cryogenic temperatures.The corrosion resistance of Alloy 316H is comparable to Alloy 316/316L and is superior to Alloy 304/304L in moderately corrosiveenvironments. It is often used in process streams containing chlorides or halides. The alloy resists atmospheric corrosion, aswell as, moderately oxidizing and reducing environments. It also resists corrosion in polluted marine conditions.Alloy 316H is non-magnetic in the annealed condition. It cannot be hardened by heat treatment, however the material will hardendue to cold working. It can be easily welded and processed by standard shop fabrication practices.

‌‌Socket welding and Threaded union‌ is a pipe connector, mainly used to connect pipes through socket welding. Its basic structure includes a socket, a socket and a socket groove. The socket and socket are located at both ends respectively, and the socket is provided with a socket groove.Manufacturing standards and application scenarios.The manufacturing standards for socket weld unions mainly include ASME B16.11 and MSS SP 83. It is widely used in pipes of different diameters, and is especially suitable for the connection of water meters, valves and other equipment. Because it adopts a socket structure, it is very convenient to install, use and maintain, and it also has high leakage resistance.
