A See Section 7. B Reduction of area does not apply on flat bars 3⁄16 in. [4.80 mm] and under in thickness, as this determination is not generally made in this product size. C The material shall be capable of meeting the required reduction of area where listed, but actual measurement and reporting of the reduction of area are not required unless specified in the purchase order. D Cold-finished shapes require only 15 %, minimum, elongation. E American Welding Society designation. F Tensile strength 70 ksi [485 MPa] minimum permitted for extruded shapes. G For bars greater than 2 in. [51 mm], a cross section, 60 ksi [415 MPa] minimum, shall be permitted. H Elongation in 2 in. or 50 mm of 12 % minimum and reduction of area of 35 % minimum permitted for cold-finished bars. I Elongation in 2 in. of 12 % minimum and reduction of area of 35 % minimum permitted for cold-drawn or cold-rolled bars. J Annealed bars shall be capable of meeting the tempered condition requirements when heat treated.
