When reviewing a JIS G 3193 PDF, the core value lies in its extensive reference tables. These tables dictate exactly how much a steel product can deviate from its nominal measurements. A. Thickness Tolerances

Steel that has not been trimmed after exiting the hot-rolling mill. These have wider permissible variations because the edges are naturally irregular.

Requirements for appearance, standard dimensions, and tolerances for hot-rolled steel products, including cut lengths from steel strips. Exclusions: This standard is specifically not applicable to flat bars International Correspondence: It is a modified version of ISO 7452:2013 , adjusted to reflect Japanese transactional practices.

Robotic welding arms and CNC plasma cutters require predictable, highly consistent material dimensions. Wide deviations cause machine jams or faulty welds.

JIS G 3193 PDF: Dimensions, Weight, and Tolerances for Hot-Rolled Steel

The standard specifies the dimensions, mass, and permissible variations (tolerances) for hot-rolled steel plates, sheets, and strips . The most recent major revision is JIS G 3193:2019 , which replaced the 2008 version and aligns closely with the international standard ISO 7452:2013 . Core Content of JIS G 3193

High-yield steel for welded structures (e.g., SM490).
