1.1 This specification covers carbon and high-strength steel shapes of structural quality manufactured by the electric-resistance forge-welding process from coils.1.2 The size range covered is described in nominal dimensions for columns, beams, and tees. Size Range, in. (mm)Web thickness0.060 to 0.500 [1.5 to 12.7]Flange thickness0.060 to 0.500 [1.5 to 12.7]Overall depth2.00 to 24.00 [50 to 600]Flange width 0.50 to 12.00 [12.7 to 300] 1.3 These shapes are intended for two classes of application: 1.3.1 Class 1—General structural use where static loading predominates.1.3.2 Class 2—Structural use where fatigue loading occurs and is a principal design consideration. ?Note 1: Caution—Because of the absence of smooth, integral, large radius fillets at the junctions of the webs and the flanges (see Fig. 1), fatigue limits of resistance forge-welded shapes in torsion, lateral loading, and flexure are usually lower than those for hot-rolled shapes of similar size and material.
