5. Stainless steel is no magnetic, without magnetism is good stainless steel? Is it not 304 if the microstrip is magnetic?
Many customers buy Stainless Steel in the market, with a small magnet, when they look at the goods, they think it is good stainless steel. Without magnetism, it will not rust, but it is a wrong understanding. E-BON the most excellent stainless steel company, which provide you with oem Stainless Steel BBQ Set.
Stainless steel belt without magnetic structure is determined, the molten steel during solidification process due to solidification temperature of different form "ferrite" "austenite martensite" with different structure including stainless steel, ferritic stainless steel, martensite "are magnetic. The austenitic stainless steel has good mechanical properties and weldability, but only from corrosion resistance, ferrite stainless steel is stronger than "austenitic stainless steel". At present, the market circulation of high manganese containing less nickel containing the so-called 200 series, 300 series stainless steel is not magnetic, but its performance and high with 304 big gap, but after treatment, 304 drawing, annealing, polishing and casting process will therefore use stainless steel band microstrip magnetic nonmagnetic stainless steel to judge is a misunderstanding, it is not scientific.

1) chemical methods:
The rust part is repassivated with acid pickling paste or spray to form chromium oxide film to restore its corrosion resistance. After pickling, in order to remove all pollutants and acid residues, it is very important to rinse properly with clean water. After all treatment, the polishing equipment is re polished and closed with the polishing wax.
A slight rust on the local gasoline and oil can also be used 1:1 mixture with a clean cloth to wipe the rust.

2) mechanical method:
Sandblasting, cleaning, annihilation, scrubbing and polishing with glass or ceramic particles. It is possible to use mechanical methods to wipe off the pollution caused by previously removed materials, polishing materials, or annihilation materials. All kinds of pollution, especially foreign iron particles, can be the source of corrosion, especially in moist environment. Therefore, the mechanical cleaning surface should be properly cleaned under dry conditions. The use of mechanical method can only clean up its surface, and can not change the corrosion resistance of the material itself.

Therefore, it is suggested that after the mechanical cleaning, the polishing equipment is re polished, and the polishing wax is closed. If you want to get more information about E-BON, you can click Stainless Steel Canister Supplier.
