NXF ASTM A240 316H /1Cr17Ni12Mo2/31609 DN15-1200 SCH10-XXS Stainless Steel 316H BW 90° Or 45° L/R S/R Butt Welding Elbow

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.

The main difference between stainless steel elbows and carbon steel elbows is the material. The chemical composition contained in the stainless steel elbows will keep the surface of the elbows from rusting and corroding for a long time. In the piping system, the elbow is a pipe fitting that changes the direction of the pipe. According to the angle, there are three most commonly used elbows: 45°, 90°, and 180°. In addition, according to the needs of the project, there are also other non-normal angle elbows such as 60°.
