|corten A steel plate
CorTen is a trade name for a steel alloy material
originally produced by United States Steel.
Corten is a weathering steel. This material is a
corrosion resistant steel, that left uncoated
develops an outer layer patina. This patina
protects the steel from additional corrosion. It
is a high strength steel alloy, and it is used
where higher strength and longer life cycle
material are desired. Especially in situations
where untreated alloys are desired. Alternately
spelled as Cor 10.
As Cor-Ten became more popular over the years
other producing mills began to develop their own
atmospheric corrosion resistant weathering steels.
ASTM stepped in and created what is considered
equivalent specifications to Cor-Ten® in most
The applicable equivalent ASTM specifications are
ASTM A588, A242, A606-4, A847 and A709-50W, which
Central Steel Service supplies in various products
including, sheet, coil, plate, steel flats,
angles, channels, pipe & tube.
