Several processing techniques of colored stainless steel
Several processing techniques of colored stainless steel 1. Water plating (mainly black, note that the color of 304 plating water is stable, slightly blue mirror surface is especially obvious, and the surface is brown with high temperature fingerprint processing) 2. Electroplating-PVD vacuum pla...Read more -
Calculation formula of the theoretical weight of stainless steel pipe
The calculation formula of the theoretical weight of stainless steel pipe: Steel pipe (including seamless steel pipe and welded steel pipe) (kg/m) W= 0.02466 ×S (D – S) D = outer diameter S = wall thickness For example: a seamless steel pipe with an outer diameter of 60 mm and a wall thickness o...Read more -

Summary of the basic types of stainless steel surface processing
Summary of the basic types of stainless steel surface processing The multiple surface processing of stainless steel broadens its application fields. Different surface processing makes the surface of stainless steel different, making it unique in its application. In the field of construction appli...Read more -
What happened to stainless steel 304, two knives are broken!
What happened to stainless steel 304, two knives are broken! 1. The blade inclination angle of the tool must be 0°, and it can be ground on a tool grinder if possible. This is the most important point. Because the friction between the chips and the groove wall is severe when the stainless steel i...Read more -
Stainless steel really does not rust? Is the medical grade and food grade reliable?
Stainless steel really does not rust? Is the medical grade and food grade reliable? Stainless steel is generally a general term for stainless steel and acid-resistant steel. Stainless steel refers to steel that is resistant to corrosion by weak media such as atmosphere, steam and water, wh...Read more -
Important: Several identification methods of stainless steel
Several identification methods of stainless steel（一） Physical identification is to determine whether it is stainless steel with the help of simple instruments and the senses according to the inherent physical and chemical properties of the product (including the whole material, residual materi...Read more -
Nickel is greatly affected by the rise and fall of stainless steel in the short-term, wait and see or short-term operations are better
Nickel fluctuated strongly overnight. The yields on US long-term Treasury bonds weakened rapidly, driving short-term risk aversion. But the crisis itself coexists, unless the market believes that global inflation makes it impossible for central banks and governments to provide more ammunition. In...Read more -
