Jis G3193 Pdf [2026]

For example, a standard plate with a width under 1,600 mm will have a much tighter thickness tolerance (often within hundredths or tenths of a millimeter) than a massive plate exceeding 2,500 mm in width. 2. Width Tolerances

Flatness is measured on a flat surface plate. The deviation is calculated as the difference between the highest point of the convex side and the actual thickness of the steel. 📥 Where to Find the PDF

Standard widths are configured based on rolling mill capabilities, typically including metrics like 1000 mm, 1219 mm, 1500 mm, 1800 mm, and 2000 mm .

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. jis g3193 pdf

For thicker plates, the plus tolerance is often larger than the minus tolerance to ensure the minimum required thickness is met. B. Width and Length Tolerances

JIS G3193 defines the permissible variations (tolerances) for the thickness, width, length, and shape of hot-rolled steel products. While other standards (like JIS G3101 or JIS G3131) define the material chemistry and strength, of the finished product. Key Details:

The standard, titled "Dimensions, shape, mass and permissible variations of hot rolled steel plates, sheets and strips," is the primary Japanese Industrial Standard for defining the physical requirements of hot-rolled steel. It serves as a foundational "umbrella" standard, referenced by specific product standards like JIS G 3101 (General Structures) and JIS G 3113 (Automobile Structural Uses) to ensure dimensional accuracy and consistency.
