Grade 444 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. Type 444 is dual stabilized with titanium and niobium.
Grade 444 stainless equivalent to austensitic grade 304 in many corrosion environments and
has lower coefficient of expansion and better thermal conductivity.
It has superior chloride stress corrosion cracking resistance to grades 304 and 316.
