Ferritic Cold Rolled Grade · Excellent Formability & Surface Finish · High Dimensional Accuracy · Global Supply
HRS Ferritic has been a leading name in stainless steel and special alloys for many years. We are a recognized IRS350 Sheet Supplier, AISI IRS350 Sheet Importer, and IRS350 Sheet Stockist, offering materials only from certified and valuable steel mills with a focus on inventory readiness and quality control.
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.
Each element in IRS350 CR plays a precise role in delivering excellent formability, surface finish and corrosion performance.
