What are corten steel pipe grades?

There are different grades of corten material available for manufacturing pipe. However, two of the most commonly used corten steel pipe grades are ASTM A847 and A423/A423M. Both of them show excellent resistance to weather and corrosion.

How long does it take for develop patina on corten pipe?

Patina is the rust like layer that develops on the corten steel surface to protect it from further corrosion. The time taken by the patina to develop on the corten steel pipe will depend on the environmental conditions and the exposure level to moisture and air. In outdoor environments with high humidity and frequent wet dry cycles, patina formation may occur more rapidly.

Can you get pre-rusted weathering steel pipe?

Yes, it is possible to get pre rusted weathering steel pipe. They have undergone an artificial aging process to achieve a weathered appearance before being used. The pre rusting process involves exposing the steel to controlled environmental conditions or applying chemical treatments to accelerate the formation of the patina. This process allows the corten steel ERW pipe to have the desired weathered appearance right from the start. It saves time and provides the aesthetics of naturally aged corten steel with the same properties.

We carry and supply several corten pipe grades with OD ranging from 1.315 to 8.625 inches and wall thickness ranging from .133 to .322 inches at best price

Difference between hot rolled and cold rolled cor ten pipe?

  • Hot rolling involves heating the corten billets to high temperatures and passing them through rollers. Cold rolling involves passing the corten steel through rollers at room temperature.
  • The hot rolling process produces larger and thicker pipe whereas cold rolling produces smoother and more precise pipe.
  • Hot rolled cor ten pipe have a coarse grain structure and may have slight surface irregularities. Cold rolled pipe have a finer grain structure and a smoother surface finish.
  • Hot rolled pipe are usually more readily available and may be more cost-effective. Cold rolled pipe may be more expensive due to the additional processing steps involved.

How do I choose the right ASTM A847 cor-ten pipe for my application?

  • The ASTM A847 cor-ten pipe must be able to offer the required level of corrosion resistance to withstand the intended environmental conditions.
  • It should have the appropriate strength and load-bearing capacity.
  • It must be of the required size, length and dimensions of the corten pipe to fit your specific application.
  • Evaluate the cost of ASTM A847 Weathering Steel Pipe and ensure it fits within your project’s budget.

What does corten pipe cost in India?

There is no fixed corten steel pipe price as it depends on market conditions, customization required and location of delivery. The price also varies with the corten steel pipe suppliers and their internal costs. You can contact Ridhi Siddhi Steel Corporation to get quality pipe made of corten steel at the most competitive prices.
