: Outlines limits for camber (lateral warpage), flatness , and out-of-square . Flatness measurements are typically made on a flat surface plate, excluding stretcher-leveled sheets.
First established in the 1960s and revised periodically (with major revisions in 1990, 2008, and 2019), this standard specifies the general tolerances and requirements for flat steel products. Without JIS G3193, a steel plate ordered from a Japanese mill might not fit into a fabricated structure designed in another country. jis g3193 pdf
The first edition of JIS G3193 was published in 1968 by the Japanese Standards Association (JSA). Since then, the standard has undergone several revisions, with the most recent edition being published in 2019. The revisions aimed to reflect changes in technology, improve the standard's clarity, and ensure consistency with international standards. : Outlines limits for camber (lateral warpage), flatness
Hot-rolled steel plates, sheets and strips - Dimensions, shape, mass and permissible variations. Without JIS G3193, a steel plate ordered from
Specifies the maximum allowable waviness or distortion across the surface of a plate. High flatness is vital for laser cutting and precision machining.
While related structural material specifications like JIS G3101 (SS400) govern chemical compositions and mechanical properties, they rely completely on JIS G3193 to dictate physical dimensions and mill limits. Key Information Overviews
