Used to identify ferritic stainless steel 430 ( Cr 16% - Ni 0.75% ) and martensitic stainless steel 410 ( Cr 11.5% ). The best inexpensive way which can help you verify stainless steel 430 vs 410 quickly. The most common test used a single drop of solution to distinguish chromium contain in this alloy. The white color will show after a few minute if Cr content is low beyond trace and identify stainless steel grade 410. But if the solution drop is no reaction occur it identify high Cr in stainless steel 430. It can be use for identify stainless steel sheet, Plate, Tank, Pipe, Wire, Valve, Fabrication and more.
