Hexagonal steel tube material classification:20No.45Number:16Manganese and other materials, each for different applications.
Hexagonal steel pipes are steel tubes with an external hexagonal shape. They are a type of special-shaped steel pipe. They are widely used in the manufacturing of nuts, mechanical accessories, and more. Hollow hexagonal bars are a general term for steel tubes with an external hexagonal cross-section and an internal circular shape. We offer both welded non-standard seamless steel pipes and seamless non-standard seamless steel pipes. Due to material differences, they can be categorized into ordinary carbon steel shaped steel pipes and stainless steel hexagonal tubes.
