The History of Chinese Stainless Steel

Stainless steel from the invention to the actual industrial application of time span of about ten years: 1904-1906 French Guillet first of Fe-Cr-Ni alloy metallurgy and mechanical properties of the groundbreaking basic research; 1907-1911, the French Portevin And British Gissen found the Fe-Cr and Fe-Cr-Ni alloy corrosion resistance and completed the Guillet research work; 1908-1911 German […]

What is the high temperature alloy?

What is the high temperature alloy? High temperature alloy is also called hot strong alloy, super alloy. The materials can be divided into three groups: iron, nickel and chromium. According to the production method can be divided into the deformation of high temperature alloy and cast high temperature alloy Classification according to the matrix elements, […]

The advantages of duplex steel

The advantages of duplex steel mainly have the following points: (1) with good corrosion resistance, its wear resistance and corrosion resistance are better than that of austenitic stainless steel. (2) enough plastic toughness needed for forming. The use of duplex stainless steel production tank or pressure vessel wall thickness, is conducive to reduce costs. Has excellent […]

Analysis on the current situation of world stainless steel production capacity and product development

In the past 30 years, global stainless steel output has been an average of more than 5% growth rate. In recent years, different regions of the world steel production is different, while the stainless steel production in Asia has a remarkable increase. Although the development of stainless steel in less than 100 years, but the stainless steel […]

Corrosion resistance of all kinds of stainless steel by

304 stainless steel is a kind of universal, it widely used for requirements of making good comprehensive properties, resistance to corrosion and formability of equipment and parts. 301 stainless steel in the deformation, showing a clear working hardening phenomenon, is used to require a variety of high strength occasions. 302 stainless steel, in essence, is a variant […]

The chemical identification method of stainless steel By

Stainless steel, it is to point to weak corrosive medium such as air, steam, water resistance and acid, alkali, salt and other chemical etching medium corrosion of the steel, also called acid-proof stainless steel. Stainless steel itself because of its corrosion resistance, high temperature resistant, wear resistant features, in our country focus on the development […]

Selection of Welding Consumable for Welding Stainless Steel By

Matching the consumable to the parent material The chemical composition of stainless steel welding consumables is matched with the base or parent material. The chemical analysis (composition) of the consumables used are usually balanced to optimise the welding process and avoid hot cracking. Austenitic stainless steel Low carbon levels are normally used to reduce the […]
