Stainless steel-Magnetism and Other Properties of Stainless Steel
Yes to varying degrees. The magnetism of stainless steel is affected by its alloying elements, atomic grain structure, and the amount of cold-working during fabrication.What are 18-8, 300-Series and 400-Series stainless steels?The American Iron and Steel Institute (AISI) has created widely accepted grades for stainless steels. These grades are identified by series numbers 100 through 600 where each series is organized by alloy and grain structure properties. Most common to the electronics fastener industry are 300-series and 400-series stainless steels. The 300-series steels have an “austenitic” metallic grain structure while 400-series have “ferritic” or “martensitic” structures. Among other alloying elements, several 300-series stainless steels contain approximately 18% chromium and 8% nickel. Thus “18-8” is a loose characterization of stainless steel grades 302-305, 316, 321 and 347. Even more general is the acronym “CRES” which typifies any corrosion-resistant steel.
