Jis G 3193 Pdf

Width variations depend on how the edges of the steel plate are processed during production:

: Flat-rolled products typically below 3.0 mm thick, supplied as cut lengths.

Understanding the JIS G 3193 Standard for Hot-Rolled Steel The standard, titled "Dimensions, shape, mass and permissible variations of hot-rolled steel plates, sheets and strips," is a cornerstone of the Japanese Industrial Standards (JIS) used extensively in manufacturing and construction. Often searched for as a JIS G 3193 PDF , this document is critical for ensuring that hot-rolled steel products meet strict dimensional and quality requirements. Scope and Application

: Specific rules on where to measure thickness (e.g., at least 25 mm from the edge for mill-edged strips).

Generally ranges from under 1.60 mm up to over 300 mm.

It explicitly does not apply to flat bars or specialized structural sections, which fall under standards like JIS G 3192 . 📏 Technical Overview: Standard Dimensions & Tolerances

Width and length tolerances depend heavily on whether the steel is finished with a (mechanically sheared/laser trimmed) or a mill edge (as-rolled from the mill). 1. Width Tolerances

Beyond simple dimensions, JIS G 3193 also specifies requirements for the shape of the steel, including its flatness and warpage. These are critical for applications where the steel must lie flat or be precisely aligned.

: Permissible variations in thickness (often categorized as under or over 4 mm), width, and length.
