NXF ASTM DIN JIS 316H/1Cr17Ni12Mo2/31609 DN15-1200 Class 150-2500 Stainless Steel 316H Forging Butt Welding Cross

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.

Butt-weld cross is a steel pipe fitting made by hot pressing or forging. The connection method is to directly butt-weld the cross to the steel pipe to ensure the stability and sealing of the connection. Butt-weld crosses are divided into equal diameter and reducing diameter. The pipe ends of equal diameter crosses have the same size, while the pipe ends of reducing crosses have the same size of main pipes, and the branch pipe ends are smaller than the main pipe. Butt-weld crosses are widely used in pipeline branches and are suitable for various industrial fields such as petroleum, natural gas, chemical industry, etc., for connecting four pipes with the same nominal diameter and perpendicular to each other.
