The standard provides detailed tables for measuring and verifying the quality of steel products:
Essentially, it acts as a "dimensional rulebook" for steel manufacturers and purchasers to ensure that hot-rolled steel products meet specific size and quality tolerances. Key Specifications of JIS G 3193 jis g 3193 pdf
Flatness is critical for automated welding or laser cutting. JIS G 3193 defines the maximum deviation per unit length (e.g., ≤ 5 mm per 1000 mm for certain thicknesses). The standard provides detailed tables for measuring and
Width and length tolerances depend heavily on whether the steel is finished with a (mechanically sheared/laser trimmed) or a mill edge (as-rolled from the mill). 1. Width Tolerances jis g 3193 pdf
