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!
