Jis G3193 Pdf Jun 2026

specifies dimensions, tolerances, and mass of hot-rolled steel sections, including:

Verify that the "permissible variations" allow for proper fit in structural applications. Key Technical Specifications of JIS G3193 JIS G3193 sets strict rules for the following aspects: 1. Dimensions and Mass

This standard is primarily used by engineers and manufacturers to ensure that steel products meet specific physical requirements. It covers: Dimensional Tolerances

The standard provides specific rules for measuring and accepting hot-rolled steel products based on their physical dimensions. 1. Scope and Application Hot-rolled steel plates, sheets, and strips. Exclusions: It does not apply to flat bars. jis g3193 pdf

Hot-rolled steel plates, hot-rolled steel sheets (including cut lengths from strips), and hot-rolled steel strips.

If you need to verify specific tolerances for a project, consulting the 2019 edition of JIS G 3193 on JSA Webdesk is recommended.

This is the most referenced section. Unlike ASTM standards that offer "A, B, or C" tolerances, JIS G3193 gives specific allowable deviations depending on the nominal thickness and width of the sheet or plate. Exclusions: It does not apply to flat bars

: Defines the theoretical mass of steel plates and sheets, generally expressed in kilograms. Obtaining the JIS G 3193 PDF

is the foundational Japanese Industrial Standard that specifies the dimensions, shapes, mass, and permissible variations (tolerances) for hot-rolled steel plates, sheets, and strips.

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. Scope and Application typically under 3 mm in thickness.

: If an engineer designs a part assuming a 10mm thickness, they need to know the maximum "minus tolerance" allowed so the part doesn't fail under stress.

Cut lengths sliced from coils or rolled directly, typically under 3 mm in thickness.
