What is Corten Steel?

CORTEN Steel is basically weather & atmosphere resistant steel which doesnt get rusted but rather develops a thin layer of rust on the exterior to prevent it from further rusting of the material and thus the material getting “pitted”.

Other names of Corten Steel are IRSM 41, this is heavily used in Railways and its applications because of its non rusting properties. The chemical properties of this material is as such that the steel will not get rust and the strength will remain intact. Railway wagons & transport containers have to remain outside in the atmosphere for months and thus they need such material that the doesnt corrode and deter. Use of normal steel is discouraged as it will get eaten up by the rust and the strength will go down thus resulting in calamities.

Steel is rusted when it gets in contact with water (H2O) in presence of Oxygen (O2). When all these are present rust is formed on the material after which it is left not suitable for use. The properties of Corten Steel are as such that the rust will never get to this material and the strength remains intact, no matter how bad the weather is.

Corten Steel for Architectural Purposes

Nowadays, Corten steel is highly used in architectural purposes. More and more architects, interior designers are using Corten for Exterior Cladding in Buildings, Malls, Stadiums and also artwork in parks, museums, gardens, etc because of its thin rust developing property on the exterior.

The rust developed on the outside gives a very ancient, rusty look and feel to the whole architecture. It is opted by a lot of people since there is no other material that gives this look. The ageing of Corten Steel changes from time to time and so gives a constant changing look to the art piece.

We provide “Pre-Weathered” Corten Steel for all architectural purposes in Width: 1250mm & all thicknesses.

IRSM 41
IRSM 41 Steel: Body panel of Coal Wagons encounter corrosive environment due to presence of sulphur and other carbonoic acid components in coal. Use of corrosion resistance steel to IRSM-41 will face the situation better due to formation of an adherent protective oxide film on the surface if it is left undisturbed.

IRSM 41 steel has following properties-
n Stronger than mild steel
n Easily weldable
n Develops its own protective film against corrosion.
