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.

‌Hexagon head bushing is a coupling with a hexagonal head that is typically used in applications requiring high-strength connections. Its design makes tightening and disassembly using a wrench very convenient. Threaded hexagon head bushings are widely used in various occasions that require high-strength connections, including but not limited to: Construction‌: In building structures, hexagon head bushing is used to connect steel bars, pipes, etc. to ensure the stability of the structure. Machinery manufacturing‌: In mechanical equipment, it is used to connect various components to ensure the normal operation of the machine. Automobile manufacturing‌: In automobile manufacturing, it is used to connect key components such as body parts and engines. In other industrial fields: such as bridges, ships, etc., joints play an important role.
