= Preferred material specification.
= Other applicable material specification, the availability of which should be confimed prior to
specification.
= Material specification does not apply.
"Minimum unless a range is shown.
'For shapes over 426 Ibift, only the minimum of 58 ksi applies.
* Groups 1 and 2 shapes only. To improve weldability a maximum carbon equivalent can be specified
(per ASTM Supplementary Requirement S78). If desired, maximum tensile stress of 90 ksi can be specified
(per ASTM Supplementary Requirement S79).
If desired, minimum tensille stress of 70 ksi can be specified (per ASTM Supplementary Requirement S81).
Groups 1, 2 and 3 shapes only.
'ASTM A618 can also be specified as corrosion-resistant; see ASTM A618.
Minimum applies for walls nominally /4-in. thick and under. For wall thicknesses over 4 in., F- 46 ksi and
F.- 67 ksi,
'If desired, maximum yield stress of 65 ksi and maximum yield-to-tensile strength ratio of 0.85 can be specified
(per ASTM Supplementary Requirement S75).
'A maximum yield-to-tensile strength ratio of 0.85 and carbon equivalent formula are included as mandatory in
ASTM A992.
Groups 4 and 5 shapes only.
*Group 3 shapes only.
"Groups 1 and 2 shapes only.
