Grade 300 (Grade 40) bars show only three marks (no grade mark) usually in the following order: 1st — Producing Mill (usually an initial) 2nd — Bar Size Number (10 mm - 36 mm [#3 - #11], 43 mm [#14], and 57 mm [#18]) 3rd — Type Steel: S for Billet (M 31 / ASTM A-615) A for Axle (M 322 / ASTM A-966) W for weldable steel (ASTM A-706) or R for Rail (M 322 / ASTM A-966) Grade 420 (Grade 60) bars must also show a minimum yield designation grade mark of either the number “4” (“60”) or one grade mark line continued for at least five deformation spaces. A grade mark line is smaller than and between the two main ribs, which are some- times on the opposite side of the bar. When a numerical grade is used, it is the 4th in order.
