| Specifications︰ | Cold-Formed Welded or Seamless High-Strength, Low-Alloy Structural Tubing with improved atmospheric corrosion resistance is commonly called several things.
Corten - This is a U.S. Steel trademark name which covers all steel products with an improved atmospheric corrosion resistance.
A588 - Several tube mills have put the A588 spec on their test reports, but A588 is the spec for structural steel shapes or plates.
A606 - This is the same basic spec as A588, but it is the same specification for coils.
A847 - This is the tube spec of steel with improved atmospheric corrosion resistance.
Requirements for A847 - 99a:
Physical requirements for round and shaped tubing:
Yield strength min PSI 50,000 (345)
Tensile strength min PSI 70,000 (483)
Elongation in 2 inches (50.8mm) Min% 19
Chemical requirements for round and shaped tubing
Elements
Heat Analysis
Product Analysis
Carbon Max 0.20 0.24
Manganese Max 1.35 1.40
Phosphorus Max 0.15 n/a
Sulpher Max 0.05 0.06
Copper Max 0.20 0.18
A847 Tubing must have an atmospheric corrosion resistance of 6.0 or higher.
The producing mill has the choice to use alloying elements to meet this requirement. The choice and use of these elements are from the producing mill and must be reported on the mill certification.
Chemicals commonly used include: Chromium, nickel, silicon, vanadium, titanium, and zirconium.
High strength-to-weight ratio. This gives the designer the ability to reduce costs thru using lighter sections for your project.
Superior corrosion resistance over regular carbon steel. Allows this weathering steel to naturally conform to the environment.
Reduction of maintenance cost. Since Corten does not have to be painted in a regular maintenance program, the lifetime cost of the project is much less than a painted steel project. Also, corten can have a longer life when exposure to the elements will be a factor.
Corten or self-weathering steel can be used in environmentally sensitive areas where leaded paint can present problems for wildlife.
Corten or self-weathering steel is a favorite of artists looking for a metal to blend in with the outdoor environment for sculptures or fountains.
