Stainless Steel Sheets

Are user selected and used, although the market price is higher than the energy used type of stainless steel outdoor khac.Kha the higher 316 stainless steel plate.

Comparison of the manufacturers, the steel company Krupp in Germany continued to improve this steel component by adding nickel to steel to improve corrosion resistance to acids and soften more easily worked. Based on this discovery that two kinds of steel grade 400 and 2 300 born shortly before the First World War.

After the war, the 20s of the 20th century, a British steel industry expert Mr. W. H Hatfield continued research and development of the idea of ​​stainless steel. By combining the different ratio between nickel and chromium in the steel sectors, he has introduced a new type of stainless steel 18/8, who 8% Ni and 18% Cr, is the familiar steel grade 304 nowadays. He is also the inventor of the 321 steel by adding titanium to steel composition ratio above 18/8.

After nearly a millennium, the advent and development, today stainless steel is widely used in all areas of civil and industrial with over 100 different steel grade.

Austenitic stainless steel is the most common. Under this line may include the steel grade SUS 301, 304, 304L, 316, 316L, 321, 310s ... It contained the minimum 7% nickel, 16% chromium, C 12:08% max. Such components created for this steel has high corrosion resistance in wide temperature range, not magnetized, flexible, pliable, easy to solder. This steel is used to make many household appliances, containers, industrial pipe, industrial ships, exterior architecture, the other buildings ...

Stainless steel Inox also known as a form of iron alloys containing minimum 10.5% chromium. It is less prone to discoloration or corrosion like other ordinary steel.

They also contain some other elements such as nickel, molybdenum, stainless steel vanadi..Mac are only symbols of steel alloy components (eg, type 304 stainless steel is familiar containing 8% Ni and 18 % Cr).

Inox (stainless steel), chemical resistant and corrosion Oy. But choosing the right type and specifications of them in each case is very important.

Not Inox no magnetic response that depends on the type. Maybe you've heard people say the word "Inox breathe" and "inox not breathe". Inox type not breathe as austenitic stainless steels, have not at least 7% Ni. This type of poor response. The remaining Inox type (Feritic and Duplex, Martensitic) are reactions from.

Choosing good stainless steel products:

- Using magnetic beads to try, kind sniffed as much iron phase, poor quality, very quickly rust. 

- Buy with stamp, label manufacturers, with product warranty.

- Stainless steel used for cooking should choose a symbol 304, stainless steel products used for cooking should not choose 430. When shopping, ask the seller to recommend the right type.

- With 2-3 layers thick bottom to snap onto the bottom without echoes, even thin bottom will create a more resonant sound. Some manufacturers make products but create a thin stainless steel plating on the bottom layer to silencer. This type is easy to detect in that though no sound but see the product picked up softer than normal sort.

- Good products are cast all in one piece, without any joints or edges bordering public eyelid. The stainless steel products "spot welding" leave burn marks at the junction dots forming the handle or eyelid borders.

Application of stainless steel

In civil:

When human life is increasingly high, stainless steel as raw materials are widely used in many fields of civil, that is:

In industry:

Stainless steel is used a lot in the industry, both heavy industry and light industry.

- Heavy industry: shipbuilding, chemical storage tanks, liquefied oxygen tank, pipeline systems and industrial gas ..........

- Light industry: food processing industry, piping food and beverages, beer tubs ...
