309s Stainless Steel Coil

300 series is generally austenitic stainless steel, the matrix to face centered cubic crystal structure of austenite structure, non-magnetic, mainly through cold processing to strengthen it, and may lead to a certain magnetic stainless steel.

Our Company provide factory competitive price.

We are willing to provide samples for testing.
