• 316 is a greatly increased resistance to chemical attack as compared to that of the basic chromium-nickel analysis. Type 316 also offers higher creep, stress-to-rupture, and tensile strengths at elevated temperatures than any other stainless steel.
• The 316 is similar to those of Type 304 except that this alloy is somewhat stronger at elevated temperatures, compare with type 304, it has Corrosion resistance improved, particularly against sulfuric, hydrochloric, acetic, formic and tartaric acids; acid sulfates and alkaline chlorides

Typical application
316 has applications in many sectors of industry, some of these include: Chlorides containing and in polluted marine environments. Desalination plants, pipework, tanks, process vessels for more aggressive corrosive liquids. Specialised process equipment in the chemical, petro chemical, pulp and paper, pollutions control and petroleum industries.

Corrosion resistance
The performance of 316 compared with other metals in various environments is shown in the table below – the corrosion rates are based on 10-years exposure.
Cold rolled
316 / 316L being extremely tough and ductile, is readily fabricated by cold working. Typical operations include bending, forming and deep drawing.
Welding
316L has good welding characteristics and is suited to all standard welding methods. Either matching (316L) or slightly over-alloyed filler wires such as 308L should be used. Weld discolouration should be removed by pickling and passivation to restore maximum corrosion resistance.
