Type 316S
- Good oxidation resistance.
- Excellent toughness even at freezing temperatures.
- Excellent welding characteristics.
- Lower carbon content.
Description
Type 316S stainless steel is an alternative to type 316, with lower carbon content. It is mainly used when the application environment involves moist corrodes in a lower temperature range than what is considered the normal “high temperature” service.
Having lower carbon content, type 316S provides reduced resistance to elevated temperatures in comparison to type 316.
Type 316S offers good toughness even in cryogenic temperatures, though it is not usually preferred in this environment.

Possible Alternatives Grades:
Type 316S stainless steel has some possible alternatives that can be used. Such as:
- 316 – Better resistance to temperatures.
- 316L – Used for specific corrosion environments.
- 316H – Higher carbon content.
FAQs:
- What is the difference between type 316 and type 316S stainless steel?
Type 316S stainless steel is used in environments with moist corrodents at a lower temperature than what is normally considered high temperature. Because of its low carbon content, type 316S provides reduced resistance to high temperatures than type 316.
- Does type 316S stainless steel rust?
Stainless steel type 316S has excellent resistance to oxidation and does not rust easily.
- How does type 316S behave to welding?
Type 316S stainless steel has excellent weldability. It can be welded by all standard fusion methods.
