Cor-ten a applies to plates up to 12.five mm in thickness, Cor-ten b applies to plates up to 50 mm in thickness.
Weathering method that because of their chemical compositions Cor-ten a and Cor-ten b steels, whilst applied unprotected, reveals increased resistance to atmospheric corrosion in comparison to unalloyed steels. That is because it bureaucracy a shielding layer on its surface under the influence of the climate.
The steel is used for diverse types of welded, bolted and riveted structures e.g. metal body systems, bridges, tanks and bins, exhaust systems, vehicles and gadget buildings.
basic recommendations for using this metal inside the unprotected condition are described in en 10025-5 and DAST rule 007.
