SUS304 Stainless Steel Sheet Hl Brushed Finish Custom Processing for Elevator and Wall Cladding Works

1)Composition: 304 contains Cr18-20%, Ni8-10.5%; 316L contains Cr16-18.5%, Ni10-14%, Mo2-3%, low carbon (<=0.03%); 2) Corrosion resistance: 316L contains molybdenum, chloride ion corrosion and pitting resistance stronger than 304, suitable for seawater, chemical, coastal environments; 304 resistant to general corrosion, suitable for food, building, indoor; 3) Price: 316L 40-60% higher than 304.

1) Composition: 201 contains Cr14-16%, Ni1-1.5%, Mn5.5-7.5% (manganese replaces nickel); 304 contains Cr18-20%, Ni8-10.5%; 2) Corrosion resistance: 201 poorer corrosion resistance, prone to rust in humid/salt spray environments; 304 good corrosion resistance, generally does not rust; 3) Price: 201 40-50% lower than 304; 4) Magnetism: 201 weak magnetic, 304 non-magnetic (may become weak magnetic after processing).

1) 2B (cold rolled matte): Cold rolled then annealed and pickled, then slight cold rolling, surface matte silver-gray, most common surface, accounts for 70%+ of stainless plate consumption; 2) BA (bright annealed): Cold rolled then bright annealed in protective atmosphere, surface bright as mirror, high reflectivity, for kitchenware, appliances, decoration; 3) No.1 (hot rolled): Hot rolled then annealed and pickled, surface rougher, for industrial equipment, structural parts.

Yes. Stainless steel plate welding notes: 1) Welding method: Austenitic stainless steel recommend TIG, thin plate can use plasma welding, thick plate can use submerged arc welding; 2) Welding material: Select same or higher grade wire/electrode (e.g., 304 uses ER308, 316L uses ER316L); 3) Welding process: Low current, fast welding, multi-layer multi-pass, control interpass temperature <=150C, avoid overheating.
