Greer Steel Company is now manufacturing cold rolled and annealed Martensitic stainless steels. We are currently processing Type 420 and have divided the specification into three different carbon levels as shown below.
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.
