Generally refers to flat-rolled steel with a thickness greater than or equal to 3.0 mm.
JIS G 3193 is rarely used by itself. It functions as a dimensional baseline that pairs with material property standards. The most common pairs include: Material Standard Description Dimensional Baseline Rolled Steel for General Structure (e.g., SS400) JIS G 3193 JIS G 3106 Rolled Steel for Welded Structure (e.g., SM490) JIS G 3193 JIS G 3131 Commercial Hot-Rolled Mild Steel Coins (e.g., SPHC) JIS G 3193 5. How to Obtain an Official, Legitimate Copy
Tolerances differ for "mill edges" (untrimmed) and "cut edges" (trimmed/resheared). jis g 3193 pdf
: Defined in standardized tables to match industrial requirements. Length : Specified for cut lengths of sheets and plates. 3. Permissible Variations (Tolerances)
When working with JIS G 3193 PDFs, several important considerations apply: Generally refers to flat-rolled steel with a thickness
: Requirements for surface quality, permissible defects, and methods for inspecting and reporting defects.
Thinner flat-rolled products, often supplied in cut lengths. The most common pairs include: Material Standard Description
: It applies to various product standards for hot-rolled steel, including those for structural uses (JIS G 3101, JIS G 3106) and automobile structural parts (JIS G 3113). Exclusions : It is specifically not applicable to flat bars .
In shipbuilding, bridge construction, and high-rise framework, minor structural thinning can compromise structural integrity. JIS G 3193 keeps these deviations within safe structural limits.
When analyzing a JIS G 3193 PDF, the document is heavily divided into tables outlining "permissible variations" (tolerances). Steel cannot be rolled to an absolute, perfect millimeter; macro-environmental factors like temperature changes during hot rolling cause slight variances. 1. Thickness Tolerances
