316 Stainless Steel Wire UNS S31600
Alloy 316 is an austenitic chromium-nickel stainless steel wire containing molybdenum which increases corrosion resistance, improves resistance to pitting chloride ion solutions, and provides increased strength at elevated temperatures.
Alloy 316 is an austenitic chromium-nickel stainless steel wire containing molybdenum. This addition increases corrosion resistance, improves resistance to pitting chloride ion solutions, and provides increased strength at elevated temperatures. Corrosion resistance is improved, particularly against sulfuric, hydrochloric, acetic, formic, and tartaric acids, acid sulfate, and alkaline chlorides. Properties are similar to those of alloy 304, except alloy 316 is somewhat stronger at elevated temperatures.

Standard Wire Finishes
Extra Clean: (XC) Extra clean is also referred to as “bright annealed” or “bright annealed and cold rolled.”
Grease (round wire only): Drawn in a heavy grease produces an “ultra-bright” finish for
decorative applications
Soap (round wire only): Soap is used as a lubricant in the drawing process and is not removed. It acts as a lubricant during the customer part forming operation. A soap finish is available in tempered products.
Plated: A variety of plating options are available.
∗Special finishes are available. Please contact Sales with your special finish and plating requests.
Forms
Continuous Coils
Cut to lengths
Precision cutting
Cold Forming
Type 316 can be readily formed and drawn.
Heat Treatment
Alloy 316 is non-hardenable by heat treatment.
Welding 316 Stainless Steel Wire
Alloy 316 is weldable by common fusion and resistance methods. It can develop
intergranular corrosion in the welded areas due to the high carbon content.
