444 is a low carbon, dual stabilized, 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 316 and good general corrosion resistance and oxidation resistance, similar to 316 in most environments. Being a ferritic stainless steel, 444 is not susceptible to Stress Corrosion Cracking. Annealed 444 is ductile and can be formed using a wide range of roll forming or mild stretch bending operations as well as the more common drawing and bending operations. 444 does not harden excessively during cold working. The steel has limited weldability and should not be used in the as-welded condition for dynamic or impact loaded structures. As with most ferritic stainless steels, 444 can undergo grain growth in the heat affected zone of weldments, which may adversely affect the mechanical properties in these zones.
