Sandvik SAF 2205SH Spring Wire
Categories:	Metal; Ferrous Metal; Duplex; Special-Purpose Steel; Stainless Steel
Material Notes:	Sandvik SAF 2205SH is a duplex (austenitic-ferritic) stainless steel which has a very good corrosion resistance, superior to that of AISI 316. The high tensile strength make it possible to reduce the size of the wire in the springs why it is good for example component in electronics. Information provided by Sandvik
