444 stainless steel is a low carbon, low nitrogen, dual stabilized ferritic stainless steel that provides pitting and crevice corrosion resistance superior to most ferritic stainless steels and some austensitic stainless steels. 444 is low carbon, dual stabilized stainless steel having a good ductility. It is widely known for its ruggedness and high tensile strength.Type 444 is dual stabilized with titanium and niobium. Type 444 is equivalent to Type 304 in many corrosion environments and has lower coefficient of expansion and better thermal conductivity.
444 Stainless Steel Sheet has good pitting welds as it is composed of 18 percent chromium and 2 % molybdenum. It has superior chloride stress corrosion cracking resistance to Types 304 and 316. It is oxidation and creep resistant at elevated temperatures making it a preferred material for the most demanding applications in automotive exhaust. The alloy’s enhanced resistance to pitting and crevice corrosion combined with its good general corrosion resistance to a multitude of environments makes it an excellent choice for a wide range of applications such as heat exchanger tubing, food processing equipment, hot water tanks, and automotive exhaust.

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
*Not all finishes are available for all alloys
