Promote transformation and upgrading with high quality development as the starting point and foothold
Affected by the epidemic, domestic logistics and transportation are not smooth, stainless steel supply end and demand end are affected, the short-term domestic stainless steel market will be dominated by weak adjustment and operation. The impact of the epidemic on the stainless steel market is staged, mainly in the first quarter, especially in February and March, and will improve in the second half of the year.
Stainless steel flat steel can be used to form various stress components according to the different needs of the structure, and also can be used as the connection between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.
Generally speaking, there are many classifications for stainless steel bars, among which, according to the surface treatment, there will be stainless steel black bar, stainless steel acid white bar, stainless steel bright bar and stainless steel grinding bar.
Brushed stainless steel plate is through mechanical treatment of stainless steel surface, making its surface like silk texture.
Stainless steel decorative pipe is also called stainless steel welded steel pipe for short. Common steel or steel strip is welded into steel pipe after being crimped and formed by the unit and mould. The welded steel pipe has the advantages of simple production process, high production efficiency, more varieties and specifications, and less equipment, but its general strength is lower than that of seamless steel pipe.
This process mainly uses the combination of chemistry and electrochemistry to treat a layer of stable compound on the surface of stainless steel. The chemical treatment mainly depends on the separate or mixed acid solution, cationic solution, etc. for rust removal. After that, the protective film was formed on the metal surface by chromate treatment, phosphate treatment, anodizing, blackening and other methods.
Stainless steel is usually divided into 5 types:
