201/202 Stainless Steel Bar

1. Product Overview

201 and 202 stainless steel bars are economical Cr-Ni-Mn austenitic stainless steels with high strength, good toughness, and moderate corrosion resistance. 💡 Both grades are commonly used in structural and decorative applications where cost-efficiency is a key factor. While 202 offers slightly better corrosion resistance and mechanical properties than 201, both are excellent choices for general-purpose and non-critical industrial applications.
