Jis G 3193 Pdf
The width of the plate or sheet (wider sheets have wider tolerances due to roller deflection). Example breakdown (Tolerances vary by precise width bands):
Width tolerances depend on how the edges of the steel plate are finished:
These are the critical aspects of the standard that steel mills and fabricators constantly use to ensure quality and compliance. For actual implementation, it is critical to consult the official document for the most current numerical values.
Evaluated by placing the plate on a level surface and measuring the maximum peak-to-valley distance per unit length. 🌐 Global Alignment: JIS G 3193 vs. ISO 7452
Continuously rolled steel wound into coils, which can be later cut to specified lengths. jis g 3193 pdf
Vary based on the nominal width and thickness. For example, plates under 1,600 mm wide with a thickness under 1.25 mm typically have a tolerance of . Flatness & Camber
JIS G 3193 is technically aligned with the international standard . However, modifications have been made for Japan's domestic industry needs.
The standard specifies the dimensions, mass, shape, and permissible dimensional tolerances for hot-rolled steel plates, sheets, and strips . Governed by the Japanese Industrial Standards (JIS) committee, this manufacturing benchmark ensures absolute consistency and structural integrity across heavy manufacturing, infrastructure, and automotive industries.
Measurement rule: For cut-edge or trimmed plates, thickness is measured at any point from the side edge. For mill-edge (untrimmed) plates, the measurement must be taken at least 25 mm from the edge. Tolerances for Width and Length The width of the plate or sheet (wider
Coiled steel intended for continuous manufacturing processes.
Unlike specific material property standards like JIS G 3101 (structural steel) or JIS G 3106 (welded structures), . It is referenced by these material standards to define what constitutes an acceptable tolerance for thickness, flatness, width, and length. What is covered under JIS G 3193?
Valid, fully translated English and Japanese PDF versions should be sourced directly from the Japanese Standards Association (JSA) or the Japanese Industrial Standards Committee (JISC) .
JIS G 3193 is a Japanese Industrial Standard that specifies the dimensions, shape, mass, and permissible variations (tolerances) for hot-rolled steel plates, sheets, and strips. In simpler terms, it defines the acceptable limits for how a steel product should look and measure after it has been manufactured. It is the definitive guide for quality control in the production of these products. Evaluated by placing the plate on a level
By integrating JIS G 3193 dimensional protocols into your procurement pipeline, you guarantee that your raw materials match your exact engineering intents, reducing scrap rates and maximizing workshop efficiency.
Thickness variation is the most heavily scrutinized metric in steel manufacturing. JIS G 3193 categorizes thickness tolerances based on two primary factors:
The core of the document is defining how accurate the hot-rolled material must be. The tolerances are generally categorized by the product's thickness and width. A. Thickness Tolerances

While JIS G 3193 is a general standard, its application is determined by individual product standards (e.g., those for structural steel, pressure vessels). It does not apply to "flat steel" (a specific category of steel product).
