Reasons and preventive measures for magnetic properties of austenitic stainless steel in cold processing

It is well known that the vast majority of stainless steel materials are suitable for cold forming. Austenitic stainless steel itself is not magnetic, but cold processed austenitic stainless steel will have strong magnetic properties, especially those made of austenitic stainless steel, such as head, elbow and so….. Why will the austenitic stainless steel suddenly appear to […]

Advantages and disadvantages of adding titanium in austenitic stainless steel

When chromium – nickel austenitic stainless steel is heated to the temperature range of 450-800 C, corrosion often occurs along the grain boundary, which is called intergranular corrosion. Generally speaking, intergranular corrosion is actually carbon element precipitated from Cr23C6 in the metallographic structure of saturated austenite, resulting in poor austenite structure at grain boundaries. Therefore, it is […]

Factors to be paid attention to in the process of solid solution processing for stainless steel pipes

During the process of solid solution treatment, stainless steel pipes need to pay attention to the influence of protective atmosphere, temperature and cooling speed. The first is the light online solution treatment procedures, stainless steel pipe in the production process caused by rolling, drawing and welding heat effect, will lead to pipe structure and mechanical property will […]

What matters to be noticed in the practical application of duplex stainless steel

Nowadays, duplex stainless steel is widely applied in various industrial fields, such as pulp and paper industry, oil and gas industry, chemical industry, dangerous goods transportation, pharmaceutical and food processing, and construction industry. In these industries, the duplex stainless steel is mainly used for the preparation of reaction containers, industrial equipment and various kinds of conveying pipes. […]

Corrosion performance of stainless steel in acid

Nitric acid is a strong oxidizing acid, strong oxidative corrosion, a lot of chemical fiber used in chemical fertilizers, dyes and other chemical industries. Stainless steel acid-resistant steel is developed from the application of nitric acid industry. Cr13 stainless steel has a certain corrosion resistance in dilute nitric acid at room temperature. Cr18 stainless steel has a […]

The condition of stress corrosion cracking is caused by stainless steel

Chromium martensitic stainless steel and ferritic stainless steel according to different conditions can cause stress corrosion cracking (mainly intergranular cracking) or hydrogen embrittlement, but this kind of stainless steel in MgCI2 or NaCI solution, resisting performance is far stronger than austenitic stainless steel, and under the condition of load stress is not strong, will not cause cracking. The austenitic stainless […]

The role of molybdenum elements in austenitic stainless steel pipe

In general, simple chromium nickel, and chromium manganese nitrogen austenitic stainless steel pipe not only used for rust and oxidation resistance of medium (such as nitric acid, etc.) conditions, the use of molybdenum austenitic stainless steel as the important alloy elements added to the further expansion of the use of steel, the effect of molybdenum is mainly […]

The chemical identification method of stainless steel By yaang.com

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 […]

Nitrogen and Molybdenum Chromium In Stainless Steel By yaang.com

Molybdenum effect Molybdenum in pure γ-Fe in the maximum solubility of about 3%, ω (C) ≈ 0.25% ~ 0.30%, the maximum solubility in austenite is about 8%. Molybdenum in pure α-Fe the maximum solubility of about 32%, and decreased with temperature can precipitate Fe3Mo2, to obtain an age-hardening systems. Molybdenum is a ferrite forming element, capacity equivalent to chromium. […]
