Usage of SS 316H Instrumentation Tube Fittings

Instrumentation Tube Fittings

Alloy 316H (UNS S31609) is a high carbon modification of Alloy 316 developed for use in elevated temperature service. The alloy has higher strength at elevated temperatures and is used for structural and pressure vessel applications at temperatures above 932°F (500°C). The higher carbon content of 316H also delivers higher tensile and yield strength than 316/316L and its austenitic structure provides excellent toughness down to cryogenic temperatures..
The corrosion resistance of Alloy 316H is comparable to Alloy316/316L and is superior to Alloy 304/304L in moderately corrosive environments. It is often used in process streams containing chlorides or halides. The alloy resists atmospheric corrosion, as well 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 harden due to cold working. It can be easily welded and processed by standard shop fabrication practices.
