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.
