316 Alloy 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.

Applications

Screening application in marine environment
Pulp and Paper Equipment
Heat exchangers
Propeller shafts, Fittings
Dyeing Equipment
Exterior Architectural components in Marine Coastal Areas.

Additional Properties

Corrosion Resistance
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
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”
