Stainless Steel 316

Additional information

UNS Number	S31600
Werkstoff Number	1.4401

Description

Stainless Steel 316 has molybdenum-bearing grade making it a fair bit more resilient to corrosive abuse than Stainless Steel 304. This is especially noticeable in highly sulfuric, hydrochloric, formic and tartaric environments where pitting usually persists. Stainless Steel 316 is extremely versatile; not only does it have strong forming and welding characteristics, but it has the ability to fold or roll so it can be easily transformed into a number of applications. Additionally, Stainless Steel 316 tends to hold up better than 304 in higher temperature environments.

Similar to Stainless Steel 304, Stainless Steel 316 is one of the more popular austenitic stainless steels. Because of its outstanding welding capabilities and toughness against corrosion, you can typically find Stainless Steel 316 in these applications: food preparation equipment, marine, coastal architecture, boat fittings, woven screens for quarrying and water filtration, heat exchangers, jet engine parts, etc.
