1: Production Details

316H (UNS S31609) is a high carbon modification of 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 316H is comparable to 316/316L and is superior to 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.
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.
In most instances the corrosion resistance of  316H will be comparable to 316/316 L and will have superior corrosion resistance to
304/304L. Process environments that do not attack Alloy 304/304L will not attack this grade. One exception, however, is in highly
oxidizing acids such as nitric acid where stainless steels containing molybdenum are less resistant. Alloy 316H performs well in sulfur
containing service such as that encountered in the pulp and paper industry.
316H also has good resistance to pitting in phosphoric and acetic acids. It performs well in boiling 20% phosphoric acid. The alloy
canalso be used in food and pharmaceutical process industries where it is utilized to handle hot organic and fatty acids where product
contamination is a concern.
316H performs well in fresh water service even with high levels of chlorides. The alloy has excellent resistance to corrosion in marine
environments under atmospheric conditions.
The higher molybdenum content of  316H assures it will have superior pitting resistance to 304/304L in applications involving chloride
solutions particularly in oxidizing environments.
