Corrosion-resistant alloys are usually made from nickel, chromium and other alloying elements, and are widely used in various fields such as chemical industry, power industry, food industry, seawater environment, etc., due to their superior corrosion resistance. The cold-rolled thin plate of corrosion-resistant alloy produced by GB/T15010-1994 is a kind of manufactured thin plate, mainly used in the fields of aviation, ships and chemical industry.
Corrosion-resistant alloys are made by adding nickel and chromium to ordinary steel to form a systematic alloy structure. The chromium element has stable properties and strong oxidation resistance, while the nickel element has strong corrosion resistance. The role of chromium is to form a chrome oxide film on the surface of the steel, so as to block the attack of acid and alkali, and the role of nickel is to cause the oxidation film to form, penetrate and protect the internal steel. In addition, other alloying elements can also be added to play a decisive role in improving the corrosion resistance of the material.
The cold-rolled thin plate of corrosion-resistant alloy is made of corrosion-resistant alloy by cold rolling. It has high strength, good surface performance, smoothness and appearance. Its surface oxidation film has excellent corrosion resistance in various environments and is not easy to rust. It is generally used in corrosive medium in aviation, ships and chemical industry.
According to GB/T 15010-1994, the base material of cold-rolled thin plate of corrosion-resistant alloy is corrosion-resistant alloy strip/sheet. Generally speaking, the strip/sheet material is obtained by hot rolling or cold rolling, and the thin plate is formed by cold rolling of the strip/sheet material. It is mainly used in the fields of aviation, ships and chemical industry. According to the use of product thickness, corrosion-resistant alloy cold-rolled thin plate is divided into: 1.5~3mm thin plate; 3~4.5mm sheet; 4.5~8mm sheet; 8~20mm sheet.
The corrosion-resistant alloys used for cold-rolled thin plates produced by GB / T 15010-1994 are usually iron-nickel-chromium alloys. They can be divided into three categories according to their chemical composition: iron-nickel alloys, iron-nickel-chromium alloys and iron-chrome-nickel alloys with trace elements. According to their different uses, the products are divided into A, B, D and F series.
In summary, the cold-rolled thin plate of corrosion-resistant alloy manufactured according to GB/T 15010-1994 has advantages of high strength, good surface performance, smooth surface and excellent corrosion resistance in various environments. It is widely used in aviation, ships and chemical industry.
