The sorting of Stainless steel material

The sorting of Stainless steel material

    

At present, the international corrosion resistance of materials is divided into three categories according to the annual corrosion rate. The first type is complete corrosion resistance, and the corrosion rate is less than 0.1 mm/year. High-quality stainless steel belongs to this kind of material; the second category is a little bad corrosion resistant, the corrosion rate is 0.1-1.0mm/year, which belongs to general stainless steel; the third type is non-corrosion resistant, and its corrosion rate is more than 1.0mm per year. We can find many counterfeit stainless steel sheet or stainless steel pipe in the market and the corrosion rate is as high as 9.67mm/year, which is a serious non-corrosion resistance. After further analyzing the composition of the product, it was found that the chromium content representing the important index of stainless steel in the product was only 10.03% and 7.1%, which was far lower than the requirement of 10.5% of the minimum demand for chromium in stainless steel. In general, an iron-based alloy with a chromium content greater than 10.5% is called stainless steel, and the chromium content of these two products is far below this lower limit. The product is not stainless steel at all.
