1.4521 / AISI 444 is a ferritic chromium stainless steel with molybdenum in addition. Equal corrosion resistance to 1.4401/4404. Excellent resistance to stress corrosion cracking caused by chlorides. 444 Stainless Steel AK SteelType 444 is a low-carbon (C), low nitrogen (N), dual-stabilized ferritic stainless steel that provides pitting and crevice corrosion resistance superior to most ferritic stainless steels and some austenitic stainless steels. 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

These initial studies established the ability of cells to attach, proliferate, and develop within the three-dimensional networks composed of 444 ferritic stainless steel fibers. However, initial attachment within the networks was observed only on the fibers and at fiber junctions (Malheiro et al., 2011; Spear et al., 2013; Symeonidou et al., 2013). Filling the inter-fiber spaces in the optimal region for magneto Ferritic Stainless Steel Properties and ApplicationsJan 26, 2020 · Group 4 (Grades 434, 436, 444, and Others) With a higher molybdenum content, the ferritic stainless steel grades in Group 4 have enhanced corrosion resistance and are used in hot water tanks, solar water heaters, exhaust system parts, electric kettles, microwave oven
May 04, 2014 · Group 4 This group includes grades 434, 436, and 444 Etc. These ferritic stainless steels contain 10 % to 18 % Cr and molybdenum (Mo) content higher than 0.5 %. These steels are Mo alloyed, for extra corrosion resistance. Cr content is mainly in the range of 17 % to 18%. Grade 444 Stainless Steel Technical Data - ASKznINTRODUCTION. CS444 is a low carbon, dual stabilised, molybdenum containing ferritic stainless steel with good ductility, toughness and resistance to sensitisation, even in the welds. With 18% chromium and 2% molybdenum, the steel has good pitting resistance and crevice corrosion resistance, similar to CS316 and good general corrosion resistance and oxidation resistance, similar to 316 in

Type 444 Stainless Steel for Flue Duct TB20-1013Finally, Type 444 stainless steel is commonly desired due to an increased temperature limit of 650 F, over the 600 F limit of Type AL29-4C [1, 2]. This increased temperature limit provides an added benefit and safety factor for Type 444 stainless steel.
