Mr.t Posted April 3, 2017 Report Share Posted April 3, 2017 (edited) Recently purchased stainless and nickel split rings from worth in size 2 and 3. I've always heard that stainless doesn't spring back like nickel does, but I've found with worth its the exact opposite ,the stainless do great.I even thought maybe they were labeled wrong .I tried testing them with a magnet because stainless won't stick to a magnet,but I found the stainless rings from worth do stick to a magnet, so they are stainless coated instead of pure stainless rings,the stainless didn't stick to the magnet as strong as the nickel so I knew they were labeled correctly so if anybody order's any I'd go with the stainless.

jwfflipper Posted April 3, 2017 Report Share Posted April 3, 2017 TYPES OF STAINLESS STEEL The three main types of stainless steels are austenitic, ferritic, and martensitic. These three types of steels are identified by their microstructure or predominant crystal phase. Austenitic: Austenitic steels have austenite as their primary phase (face-centered cubic crystal). These are alloys containing chromium and nickel (sometimes manganese and nitrogen), structured around the Type 302 composition of iron, 18% chromium, and 8% nickel. Austenitic steels are not hardenable by heat treatment. The most familiar stainless steel is probably Type 304, sometimes called T304 or simply 304. Type 304 surgical stainless steel is an austenitic steel containing 18-20% chromium and 8-10% nickel. Ferritic: Ferritic steels have ferrite (body centered cubic crystal) as their main phase. These steels contain iron and chromium, based on the Type 430 composition of 17% chromium. Ferritic steel is less ductile than austenitic steel and is not hardenable by heat treatment. Martensitic: The characteristic orthorhombic martensite microstructure was first observed by German microscopist Adolf Martens around 1890. Martensitic steels are low carbon steels built around the Type 410 composition of iron, 12% chromium, and 0.12% carbon. They may be tempered and hardened. Martensite gives steel great hardness, but it also reduces its toughness and makes it brittle, so few steels are fully hardened. There are also other grades of stainless steels, such as precipitation-hardened, duplex, and cast stainless steels. Stainless steel can be produced in a variety of finishes and textures and can be tinted over a broad spectrum of colors. 1 Quote Link to comment Share on other sites More sharing options...
