NXF ASTM A240 316H /1Cr17Ni12Mo2/31609 DN15-1200 Class 150-2500 Stainless Steel 316H Forging High Pressure Socket Welding Olet

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.

Olet of socket welding is a type of branch pipe platform, which is mainly used to replace the traditional branch pipe connection methods such as reducing tees, reinforcing plates and reinforced pipe sections. It has outstanding advantages such as safety and reliability, reduced cost, simple construction, improved medium flow path, series standardization, and convenient design and selection. It is especially widely used in high-pressure, high-temperature, large-diameter, thick-walled pipelines, and is suitable for various industrial pipeline systems.
