AISI 347 Stainless Steel Spooled Wire is a high nickel stainless steel from Goodfellow's extensive range of wires. With 13 variations available, this nickel-stabilised chromium steel offers excellent corrosion resistance and heat resistance up to 870°C. Its applications include springs, fasteners and components for high-temperature environments like gas turbines. The alloy's austenitic structure also makes it useful for cryogenic applications down to liquid nitrogen temperatures.
