Product introduction

Stainless steel is the abbreviation of stainless and acid-resistant steel, which is resistant to weak corrosive media such as air, steam and water or stainless steel.

Classification of stainless steel

The main types of stainless steel include ferritic stainless steel, austenitic stainless steel, austenitic-ferritic duplex stainless steel and so on, which have the characteristics of corrosion resistance and heat resistance. Its corrosion resistance decreases with the increase of carbon content, and the carbon content of most stainless steels is low, with the maximum not exceeding 1.2%.Stainless steel is often divided into martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel and precipitation hardening stainless steel. In addition, it can be divided into chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel. There are also special stainless steels for pressure vessels.

Weldability of stainless steel

WeldabilityDifferent uses of products have different requirements for welding performance. A kind of tableware generally does not require welding performance, even including some pot enterprises. However, most products need good welding performance of raw materials, such as second-class tableware, thermos cups, steel pipes, water heaters, water dispensers and so on.

Corrosion resistance of stainless steel

corrosion resistanceMost stainless steel products require good corrosion resistance, such as first-class and second-class tableware, kitchen utensils, water heaters, drinking fountains, etc. Some foreign businessmen also do corrosion resistance tests on products: use NACL aqueous solution to boil, pour out the solution after a period of time, wash and dry it, and weigh the weight loss to determine the degree of corrosion (note: when the product is polished, the abrasive cloth or sandpaper contains Fe, which will lead to rust spots on the surface during the test).

Polishing properties of stainless steel

In today's society, stainless steel products are generally polished during production, and only a few products, such as water heaters and drinking fountains, do not need polishing. Therefore, this requires that the polishing performance of raw materials is very good. The main factors that affect the polishing performance are as follows:1.Surface defects of raw materials. Such as scratches, pockmarks, acid pickling, etc.2.Material problems of raw materials. If the hardness is too low, it will not be easy to shine when polishing (BQ property is not good), and if the hardness is too low, orange peel will easily appear on the surface during deep drawing, thus affecting BQ property. The BQ property with high hardness is relatively good.3.After deep drawing, small black spots and RIDGING will appear on the surface of the area with great deformation, thus affecting BQ performance.

Heat resistance of stainless steel

Heat resistance means that stainless steel can still maintain its excellent physical and mechanical properties at high temperature.Influence of carbon: carbon is strongly formed and stable in austenitic stainless steel. An element that defines austenite and enlarges the austenite region. The ability of carbon to form austenite is about 30 times that of nickel. Carbon is a interstitial element, and the strength of austenitic stainless steel can be significantly improved by solid solution strengthening. Carbon can also improve the stress resistance and corrosion resistance of austenitic stainless steel in high concentration chloride (such as 42%MgCl2 boiling solution).However, in austenitic stainless steel, carbon is often regarded as a harmful element, which is mainly due to the fact that under some conditions of corrosion resistance of stainless steel (such as welding or heating at 450~850ºC), carbon and chromium in steel can form high-chromium Cr23C6-6 carbon compound, which leads to local chromium depletion and decreases the corrosion resistance of steel, especially the intergranular corrosion resistance. Therefore. Most of the newly developed Cr-Ni austenitic stainless steels since the 1960s are ultra-low carbon stainless steels with carbon content less than 0.03% or 0.02%. It can be known that with the decrease of carbon content, the intergranular corrosion sensitivity of steel decreases, and the most obvious effect is achieved when the carbon content is less than 0.02%. Some experiments also point out that carbon will also increase the pitting corrosion tendency of Cr-Ni austenitic stainless steels. Due to the harmful effect of carbon, not only should the carbon content be controlled as low as possible in the process of austenitic stainless steel smelting, but also carbon increase on the surface of stainless steel and chromium carbide precipitation should be prevented in the subsequent hot, cold and heat treatment processes.

Corrosion resistance of stainless steel

When the number of chromium atoms in steel is not less than 12.5%, the electrode potential of steel will suddenly change from negative potential to positive electrode potential. Prevent electrochemical corrosion.

Stainless steel usage:

In the field of architectural application, the surface processing of stainless steel is important for many reasons. The corrosive environment requires a smooth surface because the surface is smooth and not easy to accumulate scale. The deposition of dirt will make stainless steel rust and even cause corrosion.In the spacious hall, stainless steel is the most commonly used material for elevator decorative plates. Although fingerprints on the surface can be erased, it affects the appearance, so it is best to choose a suitable surface to prevent fingerprints from being left.Sanitary conditions are very important for many industries, such as food processing, catering, brewing and chemical industry. In these application fields, the surface must be easy to clean every day, and chemical cleaning agents are often used.Stainless steel is the best material in this respect. In public places, the surface of stainless steel is often scribbled, but one of its important characteristics is that it can be washed away, which is a remarkable feature of stainless steel over aluminum. The surface of aluminum is easy to leave traces, and it is often difficult to remove. When cleaning the surface of stainless steel, it should be cleaned along the lines of stainless steel, because some lines processed on the surface are unidirectional.Stainless steel is most suitable for hospitals or other fields where sanitary conditions are crucial, such as food processing, catering, brewing and chemical industry, not only because it is easy to clean every day, but also because it is not easy to breed bacteria. Experiments show that the performance in this respect is the same as that of glass and ceramics.
