Q:

What is COR-TEN steel?

A:

Quick Answer

COR-TEN steel, sometimes written as "Corten steel," is the registered trademark of a group of weathering steel alloys, all of which feature an outer layer that naturally rusts and protects the core from corrosion. The metal does not need painting, and forms a uniform rust-like appearance when exposed to the elements.

Full Answer

COR-TEN steel has increased resistance to corrosion as compared to other steels. It forms an oxidized top layer characterized by its dark brown color that prevents rust from penetrating to the base metal. The steel saves users money on rust prevention and maintenance as these services are not needed.

As of 2014, U.S. Steel provides three types of weathering steel, designated A 242, A 588 and A 606-4 by the ASTM International standards group. Type A 242, or COR-TEN A, is the original alloy, and type A 588, or COR-TEN B, is a newer one. Type A 606-4 is thin sheet.

The manufacturer provides all alloys in a rust-free form and they begin to rust naturally after installation upon exposure to the elements. Since the alloys require climates with alternating wet and dry periods to form a proper protective layer, they are not suitable for use in marine areas, or places with high humidity, constant fog or long periods of rain.

  • Q:

    Does stainless steel rust?

    A:

    In conditions where moisture and atmospheric conditions are normal, stainless steel does not rust, but when conditions are more extreme, corrosion may occur. Stainless steel is much more resistant to corrosion than regular alloy steels. However this does not mean there are not conditions under which it rusts.

  • Q:

    Does stainless steel contain nickel?

    A:

    Modern stainless steel contains nickel along with other elements, such as molybdenum, niobium and chromium, that help the metal resist corrosion. Nickel is merely one of the key elements that adds to the rust-resistance of steel.
