Stainless steel 316 coil and sheet is part of the austenitic family of stainless steel.
Stainless steel 316 grades contain a higher level of Nickel than 304 giving it an improved corrosion resistance over 304 grades. 316/316L sheet possesses excellent mechanical properties at sub-zero temperatures and good corrosion resistance making it a great choice for marine applications.
TIASCO stocks and supplies only dual-certified stainless steel 316 sheets certified to ASTM A240 AND ASME SA240 SA666 SA480.
AISI / ASTM / UNS /SUS 316, Euronorm 1.4401, Nom. X5CrNiMo17-12-2 stainless steel s molybdenum-bearing austenitic stainless steel. The higher nickel and molybdenum Stainless Steel content in this grade allow it to demonstrate better overall corrosion resistant properties than 304, especially with regard to pitting and crevice corrosion in chloride environments. In addition, Alloy 316/ 316L provides excellent elevated temperature tensile, creep and stress-rupture strengths, as well as outstanding formability and weldability. Stainless Steel 316L is the lower carbon version of 316 and is immune from sensitization; therefore, it is very frequently used in heavy gauge welded components.
These properties are specified for the flat rolled product (plate, sheet and coil) in ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as pipe and bar in their respective specifications.
Stainless Steel 316 Corrosion Resistance
316 stainless steel has excellent corrosion resistance at normal temperatures in ordinary atmospheric conditions withstanding some natural acids, chlorine and chloride. In more corrosive environments a Duplex grade may be a more suitable option for extra protection against pitting and crevice corrosion.
