Distinguishing good quality stainless steel and stainless steel plating

Material Stainless steel is becoming increasingly popular, many consumers favored by the form of shiny material, looks very clean.

However, there are many cases installed using not long, there are no more shiny, but tarnish, tarnished, or even rust marks and appearance of tiny holes like bursting. On the market today there are many kinds of stainless author. Basis of this product may be steel or iron sheet, galvanized outside with a layer of copper, nickel and chromium thin.

Stainless steel can distinguish "genuine" and plated with stainless steel material shine. Plated Stainless often shiny gloss while inox "genuine" little tiny bright colors.

Additionally, consumers can try using magnets. Depending on the composition of stainless steel where stainless steel products "genuine" or is smoking from or if there is only a slight magnetic attraction, the pull-out force at hand will very gently.

Plated Stainless Steel will have strong absorption, even taken to close've heard "split" because the magnet is attracted to the metal. Taking magnet will see very strong attractive forces at hand.

Those techniques can also use the hot acid about 70 degrees to test the quality of stainless steel. If you are going pitch black chromed stainless steel, while stainless steel color remains good.

Inox also rare quality!

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. As nickel price is 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 it is drawn from. To distinguish good quality stainless steel is not only 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.

In the design industry interior stainless materials have applications as used as tables, chairs and some other furniture such as office use stairs, handrail ...

The stainless steel appliances shoddy fast also tarnish, gray stained or even explode surface. However, whether or not the risk of heavy metal contamination alone can not confirm the obvious, still need accurate studies.

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 ...
