Stainless steel, as its name implies, is a type of steel that can prevent corrosion. However, there are many misunderstandings for stainless steel in the public and even distortions of the fact. At this point, the public is easy to misunderstand and do not understand the aspects of a simple explanation.
1. There are too many varieties of stainless steel specifications. Is the performance of industry chaos? This is wrong. There are varieties of stainless steel specifications, because different varieties of stainless steel are suitable for different downstream products. The variety of stainless steel is complicated, but it is a very professional performance of stainless steel field. There are also many stainless steel products, like stainless steel pipes, stainless steel valves, stainless steel elbows, etc.
2. 304/2B stainless steel is the best stainless steel? There is no so-called best stainless steel. According to downstream demand, you should choose the most suitable stainless steel varieties. For example: 304 stainless steel mechanical properties are better, which is generally more suitable for simple mechanical processing, and because of stronger high temperature corrosion resistance, 310S stainless steel is often used in high temperature corrosion environment such as in boilers. In short, what is appropriate is best.
3. Stainless steel can be anticorrosive mainly because it contains electrolytic nickel? Such understanding is not accurate. The electrolytic nickel does have corrosion resistance. However, electrolytic nickel is only used to construct austenitic crystals to improve the mechanical properties of stainless steel in austenitic stainless steel instead of corrosion resistance. Therefore, it does not contain electrolytic nickel. 400 series stainless steel does not contain electrolytic nickel, but it also is corrosion resistance. Because of the corrosion resistance of stainless steel, it mainly comes from ferrochrome elements. The ferrochrome content of regular stainless steel is more than 12%. You can have the performance of preliminary corrosion resistance.
4. Stainless steel elements only have iron, nickel, ferrochrome and carbon? According to different downstream requirements of stainless steel, the metal content of stainless steel contains copper (for mechanical, antibacterial properties), molybdenum (for high temperature resistance), cobalt (for high temperature resistance), and other elements besides the above four necessary elements. The different content of related elements will also affect the strength of the related properties.
5. Stainless steel can be ordinary welded? Generally speaking, only austenitic stainless steel can be simple welding cut, martensitic stainless steel can not be ordinary welding cut.
6. All surfaces of stainless steel have silver white luster? Not all stainless steel surfaces have silver-white luster. However, it also has a part of stainless steel without pickling polishing. Its surface looks like ordinary steel.
