Cold Rolled 444 Stainless Steel Sheet

AISI 444 Inox Sheet for Water Tank Applications

Product Overview

EN 1.4521 / AISI 444 grade stainless steel is a dual stabilized ferritic stainless steel containing 2% molybdenum. This grade offers excellent corrosion properties comparable to austenitic grades 4401/4404, with higher strength values due to molybdenum alloying.

Key Features

Excellent corrosion resistance comparable to 316 stainless steel
Superior resistance to chloride stress corrosion cracking
Excellent formability and deep drawability
Dual stabilization with titanium and niobium
Approved for drinking water applications by German (DVGW) and Swiss (SVGW) authorities

Applications

Food processing equipment, brewery and wine making equipment, hot-water tanks, heat-exchanger tubing, automotive components, solar water heaters, and drinking water systems.
