About 304 stainless steel rectangular pipe

304 stainless steel rectangular tube is a hollow steel strip, used as pipe conveying fluid, such as oil, gas, water, gas, steam, in addition, the bending and torsional strength of the same, the weight is light, so it is widely used in the manufacture of machinery parts and engineering structures. Also used for production of various conventional weapons, artillery barrel, etc..

Application

As the pipe conveying fluid, such as oil, gas, water, gas, steam.in addition, the bending and torsional strength of the same, the weight is light, so it is widely used in the manufacture of machinery parts and engineering structures. Also used for production of various conventional weapons, artillery barrel, etc.


Finish proceesing 

No.4:  Honed with 150-180 grit abrasive belt products. It has better brightness with discontinuous coarse grain, fine stripes than NO.3. Stainless steel castings used for sanding and polishing the surface.Application for Bathroom, building exterior decoration materials, electrical appliances, kitchen equipment and food equipment

HL: Polishing abrasive belt with a suitable size (150 to 320 mesh), so No.4 generates continuous hairline brushed surface.Application for Architectural decoration, elevators,building doors,etc.

BA: No clear criteria. After cold rolling through bright annealing process, and to temper rolling products, high surface reflectivity. Or mirror-polished surface with a cloth buffing wheel obtained.Application for mirrors,kitchen equipment etc

No.8: Rotary buff polishing, mirror-like surface of the polishing surface.Application for Artists use, decorative etc.
