Notes: 1. For Grade C450L0 f y =450 MPa and f u =500 MPa.
f y = yield stress used in design; f u = tensile strength used in design; as defined in AS 4100.
2. Grade C450L0 to AS 1163 is cold-formed and therefore is allocated the CF residual stresses classification in AS 4100.
3. C =Compact Section; N = Non-compact Section; S =Slender Section; as defined in AS 4100.
