302 stainless steel bright wire

Overview of 302 Stainless Steel Bright Wire

302 stainless steel bright wire is a premium austenitic grade offering enhanced corrosion resistance compared to 301 variants. This versatile bright wire features a higher nickel content, resulting in more controlled work hardening characteristics. While non-magnetic in its annealed condition, this stainless steel bright wire gradually develops magnetic properties through cold working. For applications where carbide precipitation is a concern, 304 grade wire might be preferable due to its lower carbon content.

Applications and Uses of 302 Stainless Steel Bright Wire

This high-performance stainless steel bright wire excels in numerous applications:

• Precision springs and wire forms
• Industrial screening components
• High-strength fasteners
• Specialized washers
• Durable clamps
• Reliable electrical connectors
