Product Description

Ferrritic Alloy 443 Stainless Steel Sheet Will 443 Stainless Steel rust YES

443 Stainless Steel

Another common stainless steel is 443. It is a Ferrritic alloy that consists of Chromium and Titanium, while extremely low in Carbon. Together, these elements give 443 stainless a strong resistance to corrosion, especially against moisture and salt. Although most Ferritic alloys cannot compete with Austenitic alloys in terms of durability, the high level of Chromium in 443 makes it at least as corrosion-resistant as 304. Also, when compared to 304, 443 expands even less with heat, which means less stress and less warping. Remember, since 443 has high levels of Chromium, it is magnetic. This does NOT mean, however, that it is a low quality stainless! Even with a magnet on it, Chromium is one of the most corrosion-resistant metals around!

443 Stainless Steel is one of new Ferritic stainless steel with excellent rust resistance, good formability by reducing C, while increasing Cr and adding Ti contents so that it can be approximate property to 304 grade stainless, furthermore, instead of 304 in many fields due to lower cost advantage.

Peak Metal, always treat quality as company core heart, has good experiences on supplying 443 stainless steel sheet and coil with commitments to endusers and distributors abroad for a few years, guaranteed material quality and delivery period for all our valued customers.
