Depending on the type and application, CortenA can be categorized into four types: COR-TEN A, COR-TEN B, COR-TEN C, and COR-TENB-QT, of which COR-TENA's weathering and corrosion resistance is five to eight times better than that of ordinary steel.

Corten A - Chemical Composition:

Element	% by mass	Element	% by mass
C	0.12	Al	0.015/0.06
Si	0.25/0.75	V	–
