Product Description
SUS444 Stainless Steel Sheet
AISI 444 stainless steel sheet, also known as EN 1.4521, is a dual-stabilized ferritic stainless steel containing 2% molybdenum. This grade offers excellent corrosion resistance comparable to austenitic grades 4401/4404, making it ideal for various industrial applications.
Material Specifications
Grade 1.4521 is equivalent to European code 1.4521 and American standard ASTM 444. With 18% chromium content and molybdenum alloying, this steel provides higher strength values compared to grade 1.4509 while maintaining excellent formability.
Key Features
- Excellent corrosion resistance comparable to 316 stainless steel
- Superior resistance to chloride stress corrosion cracking
- Excellent deep drawability and cold formability
- Dual stabilization with titanium and niobium
- Low work hardening rate for easier machining
- Approved for drinking water applications by German (DVGW) and Swiss (SVGW) authorities
