First India-Wide License For Corten Steel Production Issued To Tata Steel

The Jamshedpur factory of Tata Steel has been granted the first license by the Bureau of Indian Standards (BIS) to manufacture structural weather-resistant steel (Corten steel).

Shipping containers, as well as other heavy-duty weather-proof applications like rail wagon side panels, rice mill containers, building construction, street furniture, and more upscale works of art, signs, chimineas, and fire bowls, will be made from Grade WR FE 490 H steel, which complies with IS 11587.

The license given to Tata Steel to produce Corten steel is a part of a bigger initiative by India to lessen the country’s reliance on the importation of shipping containers made of Corten Steel.

What is Corten Steel?

A category of steel alloys known as corten steel was created to do away with the requirement for painting and to build a stable superficial rust coating after extended atmospheric exposure. Because of its great degree of weather and corrosion resistance, it is utilized primarily in adverse weather situations.

The term is derived from the original brand name COR-TEN, which US Steel Corporation trademarked in 1933. The letters “COR” and “TEN” stand for corrosion resistance and tensile strength, respectively—two characteristics of weathering steels.

Weathering steel Corten has developed a novel method of overcoming rust, the weakest part of steel, by actually exploiting rust.

When Corten, which has minimal requirements, is exposed to the air, rust develops initially similarly to conventional steel, but over time, the action of the alloy element causes dense protective rust to form on the surface of the steel, preventing the eventual formation of more rust.

Corten can be used without any coating since it has great weather resistance. In addition to the economic benefit of lower coating costs, it also has a calming aesthetic impact because of the protective rust color.
