AISI 444 EN 1.4521 DIN X2CrMoTi18-2 Stainless Steel Round Bars
Ferritic grade AISI 444, UNS S44400 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 conductivity. It has superior chloride stress corrosion cracking resistance to Types 304 and 316.
Applications requiring high quality corrosion resistance and
resistance to chloride stress corrosion cracking are
ideal for this alloy. Current uses include food processing, brewery
and wine-making equipment, hot-water tanks,
heat exchanger tubing and automotive components.
