Material Stainless steel is becoming increasingly popular, many consumers favored by the form of shiny material and looks very clean. However, there are many cases which installed to use not long, they don’t have shiny, tarnish, tarnished, or even rust marks and appearance of tiny holes. On the market today there are many kinds of fake stainless steel . Basis of this product may be steel or iron sheet, galvanized outside with a layer of copper, nickel and chromium thin.
We can distinguish “genuine” stainless steel with fake stainless steel by gloss surface.
Additionally, consumers can try using magnets. Fake stainless steel will have strong absorption, can heard “split” because the magnet is attracted to the metal.
Those techniques can also use the hot acid about 70 degrees to test the quality of stainless steel. If it is chromed stainless steel, its color will black while stainless steel color remains white.
Inox also types, depending on the levels of creation. Basically composition of 18% chromium stainless steel usually, 8% nickel, iron and the rest are other components. Nickel price is too expensive, so in some cases, one can replace nickel with manganese, but this substitution makes the corrosion resistance of the material is very low.
A different kind of stainless steel with 12% chrome ingredient nature also shiny but not known as stainless steel because of its magnetic attraction. To distinguish good quality stainless steel the only way is to use machines to analyze the composition and not be dependent on the acid test, try the smoke from such distinguished plated stainless steel materials.
For plated stainless steel materials, to produce more cheaply, manufacturers can use the shoddy quality plating, doping substances or not plated copper layer. The material is coated heavy metal, if mixed into the food, long days, can make the accumulation of heavy metals in the body, harmful to health and even lead to serious diseases such as liver cancer,…
