Optional Skills to buy Stainless Steel Plate Products

Introduction for stainless steel plate

Stainless steel plate is smooth on the surface and has high ductility, toughness and mechanical strength, which is corrosion resistant to acid, alkaline gas, solution and other media. The stainless steel decorative sheet is an alloy steel not easy to rust, but it isn't absolutely rust-proof. The corrosion resistance of stainless steel depends mainly on the alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal organizational structure, but chromium plays the major role. Chromium has a high chemical stability, which can form a passive film on the steel surface, which isolates the metal and the outside world and protects the steel plate being not oxidized, and to increase the corrosion resistance of steel plate. After the passive film is destroyed, the corrosion resistance will be decreased.

Precautions for using stainless steel food containers

Because the subsistence level of people is progressing, stainless steel food containers, such as spoon, knife, plates, bowls, cups, pots, sinks are gradually going into the home. Stainless steel tableware is attractive and durable, but the exceeded trace elements are also harmful to human body. The overall pass rate for stainless steel food containers produced on the market is higher, but we should also take strict precautions against chromium exceed when using stainless steel food containers. The professional stainless steel sheet supplier pointed out it is not really that the stainless steel plate doesn't rust. The stainless steel will have chemical reactions and dissolve the trace elements if being exposed to acid and alkali substances in long term. Therefore, in the use of stainless steel products, consumers should note we can't store salt, soy sauce and soup with it, do not torment the traditional Chinese medicine, do not clean it with strong alkaline or strong oxidizing chemicals, such as washing soda, bleach, sodium hypochlorite.

Consumers should really view whether the label on the packaging marks the material and the steel number when buying stainless steel products, and can use a magnet to determine. Currently, the embossed stainless steel sheet used for producing food containers is divided into austenitic stainless steel and martensitic stainless steel two kinds. The container serving food should be produced with the use of austenitic stainless steel because the austenitic stainless steel is not ferromagnetic; cutlery should be produced by martensitic stainless steel, as the martensitic stainless steel has ferromagnetic.
