316 Stainless Steel Wire Shaped, Flat, Square, Round, Fine Wire, Plated and Bare Wire ASTM A666, AMS 5524

316 Stainless Steel Alloy Wire Description

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

Additional Properties of 316 Stainless Steel Wire

Corrosion Resistance of 316 Stainless Steel Wire


See NACE (National Association of Corrosion Engineers) for recommendations

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 customer part forming operation. A soap finish is available in tempered products.
Plated: Many plating options are available.
∗Special finishes are available: Contact Ulbrich Wire Sales with 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. For best results refer to: SSINA’s “Welding of Stainless Steels and Other Joining Methods”
