Grade Overview

What is the IRS350 CR Sheet / AISI IRS350 CR Sheet?

The IRS350 Sheet is a ferritic stainless sheet with good formability and surface finish. Cold Rolled (CR) processing provides better dimensional accuracy, smoother surface quality and more consistent mechanical properties. The chromium content forms a passive oxide layer that protects against atmospheric corrosion and oxidation.
