Grade 309 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.
