| Section | Description | |---------|-------------| | | Applicable steel types and shapes | | Dimensions | Standard sizes for each shape (thickness, width, diameter) | | Shape tolerances | Straightness (bowing), flatness (for plates), out-of-square (sheared plates) | | Mass tolerance | Permissible deviation from theoretical mass (usually ±5% for plates/strips, ±3–6% for sections) | | Length tolerances | Fixed vs. random length limits | | Inspection | How to measure thickness, width, camber, etc. |
“You’d think ‘JIS G3193’ is just a boring spec, but here’s the catch: The 2003 revision changed how width is measured. Older PDFs floating online still show pre-2003 tables. If your contract says ‘JIS G3193:2010’ but your QC uses a 1990s PDF, you could reject good material—or accept bad one.” jis g3193 pdf
: Limits for both "mill edges" (untrimmed) and "cut edges". Length : Specific to sheets and plates. | Section | Description | |---------|-------------| | |
JIS G 3193 is not a material standard that dictates the chemical composition or mechanical properties of steel; rather, it is a dimensional standard. Its primary scope covers the dimensions, mass, and permissible deviations for hot-rolled steel plates, sheets, and strips. This distinction is crucial for professionals in the field. While standards such as JIS G 3101 (General Structural Steel) or JIS G 3106 (Weldable Structural Steel) define the "quality" of the steel (e.g., tensile strength and yield point), JIS G 3193 defines the "geometry."
