Product Description
443 Stainless Steel Sheet & Coil
443 Stainless Steel is a ferritic alloy containing chromium and titanium with extremely low carbon content. This composition provides strong corrosion resistance, particularly against moisture and salt. While most ferritic alloys are less durable than austenitic types, the high chromium content in 443 makes it at least as corrosion-resistant as 304 stainless steel. Additionally, 443 exhibits less thermal expansion than 304, resulting in reduced stress and warping. Despite being magnetic due to its high chromium content, 443 maintains excellent corrosion resistance and quality.
As a newer ferritic stainless steel, 443 offers excellent rust resistance and good formability through reduced carbon content and increased chromium with added titanium. Its properties approximate those of 304 grade stainless steel, making it a cost-effective alternative in many applications.
