201 stainless steel bright wire

201 stainless steel bright wire is a specialized austenitic chromium-nickel-manganese grade developed as a nickel-conserving alternative. This versatile bright wire serves as an economical substitute for 301 grade in specific tempered applications. While its relatively high yield strength limits its use in annealed conditions, 201 stainless steel bright wire particularly excels in tempered applications, especially for spring manufacturing and fastener production.

Applications and Uses of 201 Stainless Steel Bright Wire
