How to see stainless steel tableware has been corrosion
Buy stainless steel tableware, you can judge the corrosion resistance of the magnet. Attracted, the content of iron, corrosion resistance. Anyway.Select the tableware but also on its external surface finish, stainless steel tableware, no obvious drawing defects India; no mouth, fast edge bristle phenomenon; welding parts firmly, no crack; and the body with the appropriate cover pot, pot, neither loose nor tight; each item has adhesive paste, trademark, name and show specifications.

Anyway.Stainless steel can be divided into three categories: austenitic stainless steel, ferritic stainless steel and martensitic stainless steel. Stainless steel is the main component of iron, chromium, nickel alloy, in addition to manganese, titanium, cobalt, molybdenum and cadmium and other trace elements, which makes stainless steel performance is stable, with rust and corrosion resistance. Austenitic stainless steel due to the special nature of the internal structure, making it difficult to be magnetized.
