AISI 420 Stainless Steel Spooled Wire

AISI 420 Stainless Steel Spooled Wire is a martensitic stainless steel alloy wire available within Goodfellow's extensive range of wires. With 12 variations, these wires offer a range of tensile strengths, hardnesses, and corrosion resistances. The wires find use in applications requiring good corrosion resistance along with hardness and strength, such as surgical instruments, valves, and bearings. The combination of properties makes AISI 420 wires suitable for demanding environments across industrial, scientific, and medical settings.
