430 stainless steel belt
430 stainless steel belt refers to 430 stainless steel strip material with width of 600mm and below, also known as 430 stainless steel strip or 430 stainless steel strip.
The 430 stainless steel strip can be divided into two types of annealing conditions: cold rolling and hot rolling. 430 cold-rolled steel strip thickness range is 0.038-3.0mm; hot-rolled steel strip thickness range is 3.0-6.0mm, more than 6.0mm after the plate. The 430 stainless steel strip is actually a calendering material and is generally produced by stainless steel calendering manufacturers. China's definition of steel strips has changed several times with the changes in stainless steel production equipment. When the width of the rolling mill was narrow earlier, the 430 stainless steel belt represented a strip material with a width of 300 mm or less. With the widespread use of mills over 600 mm in mainland China, the definition of steel strips has evolved into strip-shaped materials up to 600 mm.

Surface classification
According to the surface features, 430 stainless steel strips can be roughly divided into the following categories:
BA—The surface gloss is excellent and has a high reflectivity, like the mirror surface, so it is also called mirror surface.
1D—The surface has discontinuous granules, also known as matte surfaces.
2D - a slightly shiny silvery white.
2B—Silver white and better gloss and flatness than 2D surfaces.
No.3—There is a good gloss and the surface is rough.
No.4—There is a good gloss and a fine grain on the surface.
HL - silvery gray with hairline stripes. and many more.
The main purpose
430 stainless steel belt is mainly used in various industrial and civil fields such as stainless steel materials with a width not exceeding 600mm. Including not limited to:
1 electronic products, cutlery, screens and burners;
2 decorative materials and outdoor advertising billboards;
3 products with anti-stress corrosion requirements;
4 building decoration parts, fuel burner parts, household appliances, home appliance parts, etc.
430 stainless steel is widely used in the manufacture of chemical equipment for the production of nitric acid, such as absorption towers, nitric acid heat exchangers, acid tanks, transfer pipes and tanks, because of its good corrosion resistance in oxidizing acid solutions, especially nitric acid. It can produce industrial pipes and tableware such as food and wine.
