: Flat bars and specific cold-rolled steel products are excluded. Technical Alignment & Modern Revisions
The standard specifies the minimum requirements for these mechanical properties, which vary depending on the type of steel and the product thickness.
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
As of the last major update, JIS G 3193:2009 is the most common version, though always check the JSA website for new amendments or revisions (e.g., 2020 or 2023 confirmations).
: General expectations for the finish of hot-rolled materials. Common Applications Construction and Shipbuilding jis g3193 pdf
For a limited time after a revision, "draft" versions may be available for public comment, but these are rarely the final PDF. Do not rely on these for commercial manufacturing.
Note: A JIS H-beam is generally slightly heavier and has different flange slopes compared to an equivalent ASTM beam. Always check the PDF before substitution.
Ensure the plate will not warp during welding. The PDF provides a flatex value. Input your length to calculate max wave height.

In the world of steel manufacturing and quality control, standards are the invisible backbone that ensures safety, compatibility, and reliability. Among the myriad of international standards, stands out as a critical document for anyone dealing with hot-rolled or cold-rolled steel sections, plates, sheets, and strips. If you have searched for the term "jis g3193 pdf" , you are likely an engineer, a procurement manager, a quality assurance officer, or a student looking for the official text of this Japanese Industrial Standard.
: Tolerances differ depending on whether the edges are mill-edged or cut-edged. Flatness and Shape Key Information Overviews As of the last major
: Variations allowed based on the product's width and nominal thickness. Width and Length
Tolerances are the allowed deviations from the nominal size.
The scope of JIS G 3193 is comprehensive. It doesn't just tell you what steel you're getting; it dictates the exact degree of imperfection allowed. The key areas specified in the standard include:
