ASTM A240 Grade 316L (S31603) Stainless Steel Hot and Cold Working

Type 316/316L is a molybdenum-containing austenitic stainless steel intended to provide improved corrosion resistance relative to Type 304/304L. 316L (S31603) Stainless Steel is used in the oil and gas and chemical industries for its cost effective corrosion resistance and ease of fabrication.

Possible alternative grades to 316 stainless steel

Grade
Why it might be chosen instead of 316?
317L
Higher resistance to chlorides than 316L, but with similar resistance to stress corrosion cracking.
Applications of ASTM A240 Grade 316L:

1, Chemical processing, equipment
2, Laboratory benches and equipment
3, Rubber, plastics, pulp paper machinery
4, Pollution control equipment
5, Boat fittings, value and pump trim
