Hot rolling and cold rolling 304 stainless steel plate forming process
Hot rolling and cold rolling are the process of forming steel or steel plate, they have a great impact on the structure and properties of steel, steel rolling is mainly based on hot rolling, cold rolling is only used for the production of small steel and sheet. 1. The advantages of hot rolling can destroy the casting structure of the ingot, refine the grain of the steel, and eliminate the defects of the microstructure, so that the 304 stainless steel plate is dense and the mechanical properties
Classification of stainless steel pipe
Classification of stainless steel pipe: stainless steel seamless steel pipe and stainless steel welded steel pipe (welded steel pipe) the basic two categories. According to the outer diameter shape of the steel pipe can be divided into round pipe and shaped pipe, widely used is round steel pipe, but there are also some square, rectangular, semicircular, hexagonal, equilateral triangle, octagonal and other shaped steel pipe.
Stainless steel pipe welding points
1. The use of vertical external characteristics of the power supply, DC using positive polarity (welding wire to the negative electrode). 2. It is generally suitable for the welding of thin plates below 6mm, with the characteristics of beautiful weld molding and small welding deformation.
Stainless steel industrial pipe has the function
Stainless steel industrial pipe has a lot of functions, which is also the reason why stainless steel industrial pipe is widely used, so what is the function of stainless steel industrial pipe? Let's take a look.
