Products Description
Corten B Corten Steel Pipe is a high-strength, low-alloy steel pipe renowned for its excellent weathering properties. The pipe surface can naturally form a dense protective rust layer, which effectively enhances durability and aesthetic appeal while reducing maintenance requirements.
As a low-carbon alloy steel pipe, Corten B is primarily composed of iron, with added alloying elements such as copper (0.25–0.55%), chromium (0.40–0.65%), and nickel (≤0.65%). These elements provide it with unique atmospheric corrosion resistance.
In terms of specifications, Corten B Corten Steel Pipes are typically available in outer diameters ranging from 21.3 mm to 610 mm and wall thicknesses from 2 mm to 60 mm, meeting a wide range of engineering needs. Its mechanical properties are outstanding, with a typical tensile strength of 485–620 MPa, a yield strength of no less than 345 MPa, and an elongation of around 20%.
With these characteristics, Corten B Corten Steel Pipe is widely used in bridges, architectural structures, containers, industrial equipment, and various outdoor environments, combining structural reliability with modern aesthetic appeal.
