The difference between stainless steel angle bar and stainless iron angle bar

DataTime:[12/5/2017]

Stainless steel angle bar as a form of stainless steel products, the current application areas are increasing. And we say stainless steel usually refers to stainless steel and acid resistant steel. Stainless steel is able to withstand atmospheric, steam and water and other weak medium corrosion of steel, acid proof steel refers to acid, alkali, salt and other chemical corrosive medium corrosion of steel.

Stainless steel since its inception in twentieth Century, has experienced a hundred years of development. The invention of stainless steel can be regarded as one of the great achievements in the history of world metallurgy. The development of stainless steel has laid a very important material and technological foundation for the development of modern industry and the progress of science and technology. So far, there are many kinds of stainless steel, and their performance is obviously different. In the process of continuous development, a number of major systems have been formed.

According to the organization structure, can be divided into martensitic stainless steel (including stainless steel), ferritic stainless steel, austenitic stainless steel and austenitic and ferritic duplex stainless steel four categories; stainless steel according to the main chemical compositions and some characteristic elements of the classification can be divided into stainless steel, stainless steel, nickel chromium chromium chromium nickel molybdenum stainless steel and low carbon steel, stainless steel, stainless steel and high molybdenum high purity; according to the characteristics and application of classification can be divided into stainless steel, stainless steel, resistant to sulfuric acid nitric acid resistant stainless steel, stainless steel, pitting corrosion resistance to stress corrosion of stainless steel, stainless steel etc.; according to the classification features of stainless steel, stainless steel, divided into low temperature non magnetic stainless steel free cutting stainless steel, stainless steel, superplasticity.

The commonly used classification methods are classified according to the features of the stainless steel structure, the chemical composition and the combination of the two. Mainly divided into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel and precipitation hardening type stainless steel, etc., or divided into chromium stainless steel and nickel stainless steel.

Do not rust and people often say that the "iron", is actually the scrap iron, lead, steel and other materials recovered after two times of processing recycled, then by removing the magnetic treatment, because the traditional methods of detection is to use stainless steel magnet, so stainless iron by this method is unable to distinguish, so he will deceive fool, many of the engineering material, into the decoration of the site in a flagrant way.

In the market now "stainless steel" products can have a certain share is because of its cheap work, but look at the material tensile strength are GB stainless steel 530- 620MPa, GB 7075 Aluminum Alloy 540 - 560MPa, and "stainless steel" is only 160 -180MPa. The tensile strength of stainless steel can not even reach the 1/3 strength of stainless steel, which can easily lead to accidents. Therefore, in the construction industry, we must resolutely prohibit the use of "stainless iron products.".
