Grade 330 Stainless Steel Wires
STAINLESS STEEL WIRE FOR SPRING
The corrosion resistance of stainless steels removes the
requirement for any additional protective coatings making them the
ideal material for springs operating in a range of corrosive
conditions, high temperatures and in locations where maintenance
and replacement are difficult.
