Duplex 1.4462 (220Stainless Steel Sheets - Top Quality from China Suppliers & Factory
Product Details
Some quick highlights:
1) Super strong
With a yield strength of 450 MPa or more, these sheets let you keep things lightweight but still sturdy.
2) Excellent corrosion resistance
Thanks to their high chromium (22%), molybdenum (3%), and nitrogen (0.18%) content, they stand up to acids, chlorides, and other tough chemicals.
3) Temperature friendly
They can handle from -50°F all the way up to 600°F (-46°C to +316°C) without breaking a sweat.
4) Forming and welding
Easy to work with using common methods like TIG and MIG, making fabrication a breeze—even for complex shapes.
You can get them in thicknesses from 0.5mm up to 40mm, and widths up to about 8 feet (2438mm). And yes, they meet ASTM A240 / ASME SA-240 standards. Typical uses? Pressure vessels, heat exchangers, offshore platforms, and chemical tanks—pretty much anything that can’t afford to fail.
