EN 1.4521 Cold Rolled Stainless Steel Sheets AISI 444
444 is a low carbon and low nitrogen ferritic stainless steel containing 18% chromium, 2% molybdenum.
The alloy is stabilized with additions of columbium and titanium for resistance to intergranular corrosion.
One big advantage of the 444 stainless over austenitic stainless steels, such as 304 and 316 alloys,
is the practical immunity of the 444 stainless alloy to chloride stress corrosion cracking (SCC).
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 choose for a wide range of applications.
Some of the more common applications include heat exchanger tubing, food processing equipment,
and hot water tanks. The alloy's resistance to hot corrosion combined with its good creep resistance makes
it an excellent choice for automotive exhaust applications.
SPECIFICATIONS
444 stainless is designated as UNS S44400 in ASTM specifications A240, A268, and A276.
The alloy is also covered by ASME Specifications SA 240 and SA 268 and is listed in Section II,
Part D for Section VIII, Division 1 use to a maximum temperature of 650°F.
