Stainless Steel Grade 304 is the standard 18/8 (18% chrome, 8% nickel) austenitic stainless steel. It is a non-magnetic alloy in the annealed condition but becomes magnetic as it is cold worked. It is the most commonly used of all stainless grades. T304 can be easily welded and is the choice for many deep drawn, spun or formed parts due to its high ductility.

Tempered Condition: 304 can be provided in the tempered condition. Please refer to Ulbrich Technical Services for more information.
304 has excellent corrosion resistance and is used in many corrosive environments and atmospheres. Please refer to NACE (National Association of Corrosion Engineers) for recommendations.
# 1 –Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
# 2D – Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process.
# 2B –Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D.
#BA - Bright annealed cold rolled and bright annealed #CBA - Course bright annealed cold rolled matte finish and bright anneal
#2 - Cold Rolled
# 2BA – Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part.
Polished - Various grit finish for specific polish finished requirements
304 is ductile and can be cold worked by stamping, drawing, bending or forming methods.
