(like thickness limits) for a particular steel grade under this standard?
Standards are living documents, and JIS G 3193 is no exception. It has a long history, first established on July 30, 1954, with major revisions occurring in 1990, 2005, 2008, 2019, and most recently on . Therefore, if you are searching for the JIS G 3193 PDF, the version you most likely need—and the one currently in effect —is JIS G 3193:2025 .
Unlike material chemistry standards (like JIS G3101 for SS400 or JIS G3106 for SM490), JIS G3193 does not specify the mechanical properties (tensile strength, yield point) of steel. Instead, it acts as a . It establishes the standard sizes, theoretical mass calculations, and allowable tolerance limits for a wide range of hot-rolled steel shapes.
This standard provides the industry benchmarks for the physical properties of hot-rolled steel products. While other standards (like JIS G3101 ) define the chemical and mechanical properties of steel, focuses strictly on the geometry and weight of the finished product.

Legally, JIS standards must be purchased (via JSA or local standards bodies), but many technical forums share for reference. If you want a legitimate excerpt or help interpreting a specific table, feel free to ask.

: Rules for measuring how "straight" or "flat" a sheet must be. This is critical for automated fabrication processes like laser cutting or robotic welding.
: Receiving departments use these tables to inspect incoming shipments. If a plate is thinner than the G3193 allowance, it can be rightfully rejected. How to Access the Standard
When you download or consult a JIS G3193 PDF, the core value lies in its comprehensive tolerance tables. A. Thickness Tolerances Therefore, if you are searching for the JIS
JIS G3193 also covers the permissible crown and flatness of plates and sheets to prevent "waviness" or bowing, which is crucial for structural applications. 3. Why Access the 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.
