Hexago管是一个一般术语部分与cr钢管oss-sectional shapes other than round pipes, including welded shaped pipes and seamless shaped pipes. Because of the material, the stainless steel special-shaped tube is generally made of 304 or more materials, and the hardness of 200 and 201 materials is strong and the forming is more difficult.

Hexagonal tubes are widely used in various structural parts, tools and mechanical parts. Compared with round pipes, stainless steel special-shaped pipes generally have larger moments of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce structural weight and save steel.
