Product Description

AISI 443 SUS443 Tts443m Stainless Steel Coil Strip

About 443 Stainless Steel

443 stainless steel is a ferritic alloy composed primarily of Chromium and Titanium with extremely low Carbon content. This unique composition provides exceptional corrosion resistance, particularly against moisture and salt environments. While most ferritic alloys typically offer less durability than austenitic varieties, the high Chromium content in 443 stainless steel delivers corrosion resistance comparable to 304 grade stainless steel.

Compared to 304 stainless, 443 exhibits lower thermal expansion, resulting in reduced stress and warping under heat. The material's magnetic properties, resulting from its high Chromium content, do not indicate inferior quality—Chromium remains one of the most corrosion-resistant metals available.

As a newer ferritic stainless steel, 443 offers excellent rust resistance and good formability through optimized Carbon reduction and Chromium enhancement with Titanium addition. These properties make it a cost-effective alternative to 304 stainless steel in numerous applications.
