industrial steel pipe,
seamless steel pipe
Best selling stainless steel Welding And Seamless High Pressure Stainless Steel Pipe 321
321 stainless steel is equivalent to China's 0Cr18Ni10Ti stainless steel pipe.
It is used to manufacture high quality carbon structural steel seamless steel tubes for hot rolling and cold drawing (rolling) of superheated steam pipe, boiling water pipe and locomotive boiler superheated steam pipe, large smoke pipe, small smoke pipe and arch brick.
Chemical Composition about stainless steel pipe
NO.1: surface treated with heat treatment and pickling after hot rolling.
Generally used for cold rolling materials, industrial tank tanks, chemical industrial equipment, etc.
NO.2D: matt cold rolled products obtained by heat treatment and pickling after cold rolling.
Used for automobile parts, decoration materials, pipes, etc.
NO.2B: NO.2D products after temperature-adjusted rolling have better gloss and flatness than NO.2D surfaces.
The surface treatment with improved mechanical properties satisfies almost all USES.
NO.3: NO.2D surface is ground by NO. 100~120 grinding band, with good gloss and discontinuous coarse grain.
Used for interior and exterior decoration, electrical products and kitchen equipment, etc.
NO.4: NO.2D surface after 150~320 abrasive belt grinding products, with better gloss and discontinuous coarse lines, stripes smaller than NO.3.
Used for elevator decoration, kitchen equipment, interior and exterior decoration, electrical products, etc.
HL: no.2d surface is continuously ground by polishing sand belt with appropriate particle size, and products with long continuous grinding stripes (subdivided 150~320).
Mainly used for building decoration, elevator decoration, etc.
BA: after cold rolling, a bright annealing is applied and the product is obtained through leveling.
The surface has excellent gloss and high reflectance.
It's like a mirror surface.
Used for household appliances, mirrors, kitchen equipment, decorative materials, etc.
Used in the field machines of chemical, coal and petroleum industries with high requirements for corrosion resistance in the grain boundary, heat resistant parts of building materials and parts with difficulty in heat treatment, such as:
1. Oil exhaust combustion pipeline
2. Engine exhaust pipe
3. Boiler shell, heat exchanger and heating furnace components
4. Silencing parts for diesel engines
5. Boiler pressure vessel
6. Chemical truck
7. Expansion joint
8. Spiral welded pipe for furnace pipe and dryer
