Stainless Steel Sheet Or Coil Grade 444 For Hot-Water Tanks
Strip, Coil, Foil, Wire, ASTM A268, ASTM A240
Food processing, brewery and wine making equipment, hot-water tanks, heat-exchanger tubing and automotive components
Type 444 is a low carbon, low nitrogen, ferritic stainless steel that provides pitting and crevice corrosion resistance superior to most ferritic stainless steels. Applications requiring superior corrosion resistance and resistance to chloride stress corrosion cracking are ideal for this alloy.

FINISHES
| # 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 |
| 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. |
