How to Specify Steel Billets and Round Bars
Billet enquiries should state the grade, governing standard, square size, cut length, condition, quantity and downstream forging or rolling route. Round-bar enquiries should state the grade, diameter, length, tolerance, straightness, surface or heat-treatment condition and application.
Published references include 80 × 80, 100 × 100, 125 × 125 and 160 × 160 mm square billets and a 25–66 mm general round-bar diameter range. Final combinations require confirmation.
