Special Features of FUSHUN METAL's 304L Wire

Our Stainless Steel 304L Wire offers several distinctive advantages that set it apart from conventional wire products:

Low Temperature Performance

One of the outstanding characteristics of our 304L wire is its exceptional performance at cryogenic temperatures. Unlike many materials that become brittle at low temperatures, our 304L wire maintains its ductility and toughness down to -196°C (liquid nitrogen temperature), making it ideal for aerospace, medical, and scientific applications requiring reliable performance in extreme cold environments.

Superior Corrosion Resistance

Our 304L stainless steel wire provides excellent resistance to a wide spectrum of corrosive media:

• General Corrosion: Exceptional resistance to atmospheric conditions, most organic compounds, and many inorganic chemicals.
• Intergranular Corrosion: The low carbon content significantly reduces carbide precipitation during welding or heat exposure, preserving corrosion resistance in heat-affected zones.
• Stress Corrosion: Good resistance under most service conditions, though care should be taken in environments with high chloride concentrations at elevated temperatures.
• Crevice Corrosion: Good resistance in moderate environments.

Advanced Drawing Technology

FUSHUN METAL employs proprietary drawing technologies to produce wire with exceptional characteristics:

• Ultra-Smooth Surface Finish: Our specialized drawing processes and diamond die technology create wire with superior surface quality, minimizing imperfections that could affect performance.
• Consistent Mechanical Properties: Precisely controlled drawing parameters ensure uniform properties throughout the entire length.
• Exceptional Dimensional Accuracy: Advanced measurement and control systems maintain tight tolerances even on the finest diameter wires.
• Optimized Microstructure: Our processing techniques produce a refined grain structure that enhances mechanical properties and performance.
