General
Type 316 is an austenitic chromium-nickel stainless steel containing molybdenum. This increases general corrosion resistance, improves resistance to pitting from chloride ion solutions, and provides increases strength at elevated temperatures. This alloy is stronger at elevated temperatures. Corrosion resistance is improved, particulary against sulfuric, hydrochloric, acetic, formic and tartaric acids; acis sulfates and alkaline chlorise.
Typical Uses
Exhaust manifolds, furnaces parts, heat exchangers, jet engine parts,pharmaceutical and photographic equipments, valve and pump trim, chemical equipment, digesters, tanks, evaporators, pulp, paper and textile processing equipment, parts exposed to marine atmospheres and tubing.
Specifications
AM5524, ASTM A 240, ASTM A 666
Available Form
Thickness: 0.25mm - 6.35mm Width: up to 1219mm
Corrosion Resistance
Type 316 Stainless Steels exhibit better corrosion resistance then Type 304. They provide excellent pitting resistance and good resitance to most chemicals involvedin paper, textile and photographic industries.
Formability
Type 316 can be readily formed and drawn.
Weldability
The austenitic class of stainless steels is generally considered to be weldable by the common fusion and resistance techniques. Special considerations is required to avoid weld "hot cracking" by assuring formation of ferrite in the weld deposit. These particular alloys are generally considered to have poorer weldability then Type 304. A major difference is the higher nickel content for these alloys which requires slower arc welding speed and more care to avoid hot cracking. When a weld filler is needed, AWS E/ER 308 is often specified.

General
Type 304 is a variation of the basic 18-8 grade, Type 302, with a higher chromium and lower carbon content. Lower carbon minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion.
Typical Uses
Architectural mouldings and trim, kitchen equipment, welded components of chemical, textile, paper, pharmaceutical and chemical industry processing equipment.
Specifications
AM5513, ASTM A 240, ASTM A 666
Available Form
Thickness: 0.25mm - 6.35mm Width: up to 1219mm
Corrosion Resistance
These steels exhibits excellent resitance to a wide range of atmospheric, chemical, textile, petroleum and food industry exposures.
Formability
Type 304 have very good drawability. Their combination of low yield strength and high elongation permits successful forming of complexshapes. However, these grade work harden rapidly. To releve stresses produces in severe forming or spinning, parts should be full annealed or stress-relief
annealed as soon as possible after forming.
Weldability
The austenitic class of stainless steels is generally considered to be weldable by the common fusion and resitance techniques. Special considerationsis required to avoid weld "hot tracking" by assuring formation of ferrite in the weld deposit. Type 340 are generally considered to be the most common alloy of this stainless class. When a weld filler is needed, AWS E/ER 308 is often specified.
