304 stainless steel sheet thickness chart
1. Introduction
Stainless Steel 304 Sheets are one of the most widely used austenitic stainless steels due to their excellent corrosion resistance, formability, and weldability. SS 304 contains chromium and nickel, which provide superior resistance to oxidation and corrosion in a wide range of environments. These sheets are extensively used across industries such as food processing, chemical, construction, automotive, and household applications.
