Product Description

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.

Air Heater Tube. This product is used in industrial combustion applications where intake gases are preheated by using the heat from exhaust gases.

The product is available is the size and gauge combinations that best suit the design of your system. Some of the highlights of our Air Heater Tube include:

Scope  
COR-TEN A applies to plates up to 12.5 mm in thickness, COR-TEN B applies to plates up to 50 mm in thickness.  

Definition  
Weathering means that due to their chemical compositions COR-TEN A and COR-TEN B steels, when utilized unprotected, exhibits increased resistance to atmospheric corrosion compared to unalloyed steels. This is because it forms a protective layer on its surface under the influence of the weather.  

Applications  
The steel is used for various types of welded, bolted and riveted constructions e.g. steel frame structures, bridges, tanks and containers, exhaust systems, vehicles and equipment constructions.  
Basic guidelines for the use of this steel in the unprotected condition are described in EN 10025-5 and DASt rule 007.

In order to obtain fine grain structure a sufficient amount of nitrogen absorbing elements is added (e.g. ≥0.02% Al).  

Mechanical Properties, in the state of delivery condition  
At room temperature for plates ≥3mm in thickness (transverse test specimans, according to EN 10002). Requirements to hot rolled plates ≤3mm in thickness according to EN 10025-5.

In case of cold rolled material the yield point is min. 310 Mpa and the tensile strength min. 445 MPa. Furthermore cold rolled sheets ≤3mm in thickness made of steel grade COR-TEN A-F for increased demand to the cold formability is available.  

Mechanical properties:

  • Yield point min. 275 Mpa
  • Tensile strength min. 410 Mpa
  • elongation min. 25%
  • Tolerances on dimensions and shape according to EN 10131.

The notched-bar impact energy is determined on ISO-V longitudinal test specimens at a temperature of - 20°C as an average of three tests. For product thicknesses ≥10mm the average value is at least 27 J. For thicknesses between 10mm and 6mm, the minimum impact value is reduced proportionally to the specimen width (product thickness).  

No impact test is performed on products below 6mm in thickness.   

Number of Tests

  • 1 tensile test
  • 1 test specimen per 40 t from each heat*)
  • Notched bar impact test
  • 1 set specimens per 40 t from each heat *)
  • (3 specimens) (at test temperature -20°C)
