Application of duplex stainless steel

Duplex stainless steel with its excellent corrosion resistance, high strength and easy processing and other excellent performance, in many areas to replace austenitic stainless steel, the market prospect is very broad. The annual output of duplex stainless steel in the world is only about 1% of the total output of stainless steel. Since 1990, the annual […]

Why do stainless steel pipes rust?

Stainless steel refers to the resistance of air, steam, water and other corrosive medium and weak acid, alkali, salt and other corrosive medium corrosion of steel, also known as stainless acid resistant steel. In practical applications, the corrosion resistance of steel is often referred to as corrosion resistant stainless steel, and the chemical resistance of the […]

Application of Duplex Stainless Steel in Oil and Natural Gas

In recent years, duplex stainless steel has not only been widely used in major oil companies, the main pipeline system development, and is the main material for offshore oil production and transportation. Standard duplex stainless steel in the sweet, wet, acid service environment performed well. While ordinary carbon steel due to high internal corrosion rate, although the […]

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 […]
