Stainless Steel Processing
These steels are processed using our high-powered, reversing cold rolling mills which can produce very close gauge tolerances. In our state-of-the-art specialty strip mill, we can supply these spheroidized steels with a variety of surface finishes, standard and special edges, in either coils or cut-to-length sheets.
Martensitic stainless steels are used mostly for cutting tools, blades, knives, scissors, files, and for many other applications requiring good sharp edge retention, and/or high strength properties. These steels are almost always heat treated and are air-hardenable. The corrosion properties are optimum in the heat treated state.
