304/316L Stainless Steel Octagonal Bar
Description
Octagonal stainless steel bars are made of 316L or 304 stainless steel through cold drawing process. The octagonal structure makes it relatively high in torsion resistance, strong in load-bearing capacity, and difficult to process. 304 octagonal bars are general-purpose octagonal bars, while 316L octagonal bars are low-carbon stainless steel bars, which are more suitable for welding and highly corrosive environments. Stainless steel octagonal bars are often used in food processing, construction, marine engineering and other fields.
Application：
- Food processing
- Construction
- Marine engineering
