OPT-in Chromium Mystery





Chromium is essentially Stainless Steel and the grade shown on the packaging is the type of stainless steel and the amount of  Chromium or other materials are in it . Ours shows a "Grade 24" which puts it in a a Chrmomium containing stainless steel category.  Specifically

"Ferritic Stainless SteelThe family of Ferritic stainless steel alloys has chromium content of more than 10.5% and a low carbon content. They are plain chromium grades, display magnetic properties and cannot be hardened. They are not suitable for fabrication and are moderately resistant to corrosion. They can be polished and are used for the manufacture of automotive exhausts and sometimes for welding applications. "

  1. Hi Freddy. This wasn't actually an "Opt In" post (just a heads up for class that the materials had arrived) but I'll score you points on it since you did some reasonable investigation of it. Attention to detail is important for military work so please keep that in mind as a lesson from this.

    What questions could we ask on this subject that could give it more depth to be "Opt In" worthy?
