NLMK Group, an international metallurgical company, has started testing a zinc-aluminum-magnesium coating (TsAM) for cold-rolled steel in cooperation with the Institute of Physical Chemistry and Electrochemistry (IPCE) of the Russian Academy of Sciences. The new coating compared to zinc makes rolled steel three times more resistant to corrosion, and also protects the metal from cracking during machining due to its high ductility.
ZAM-coated rolled steel was developed by NLMK Group R&D specialists in research the company's centers in Belgium and Russia.
During the tests, samples of coated rolled products will be exposed to an increased content of sulfur dioxide in the air, corrosive effects of sea salt aerosol, high air humidity at low temperatures.
One of the areas of application of the new coating is the production of light steel thin-walled structures. The structure of the coating minimizes the effect of oxygen and moisture on the steel, which allows for better protection of building structures from corrosion. In addition, ZAM-coated steel is used as a basis for the production of polymer-coated rolled products, ensuring the durability of products made from it up to 50 years.
Tests are carried out in accordance with Russian and world standards, the new product is planned to be introduced to market in 2022.
