The JIS G 3193 standard, titled "Dimensions, shape, mass and permissible variations of hot rolled steel plates, sheets and strips", is a fundamental Japanese industrial specification that defines the physical requirements for hot-rolled steel products. It is widely used in global manufacturing to ensure consistency in the dimensions and surface quality of steel used in construction, automotive parts, and machinery. 1. Scope and Core Purpose

The standard provides a uniform framework for measuring and certifying the physical properties of hot-rolled steel. Unlike other JIS standards (such as JIS G 3101), which focus on chemical composition and mechanical strength, JIS G 3193 specifically targets geometrical accuracy and tolerances.

Materials Covered: Steel plates, steel sheets (including cut lengths from strips), and steel strips. Exclusions: It is explicitly not applicable to flat bars.

Relationship to International Standards: It is based on ISO 7452, but modified to align with Japanese transaction practices. 2. Standard Dimensions and Units

JIS G 3193 outlines standard nominal dimensions for three primary categories:

Thickness: For steel strips and cut lengths, a maximum thickness of 12.7 mm is typically applied.

Width: Defined in standardized tables to match industrial requirements. Length: Specified for cut lengths of sheets and plates. 3. Permissible Variations (Tolerances)

A critical aspect of the PDF is the detailed tolerance tables for manufacturers. HOT ROLLED STEEL SHEET

JIS G 3193 is the Japanese Industrial Standard for the dimensions, mass, and permissible variations of hot-rolled steel plates, sheets, and strips. While it doesn't define the chemical composition of the steel (which is handled by other standards like JIS G 3101 for SS400), it provides the physical framework for how these products should be measured and what tolerances are allowed. Scope and Application

This standard applies to hot-rolled steel plates and sheets (including cut lengths) and steel strips. Not Applicable To: Flat bars.

Connection to International Standards: It is based on ISO 7452, but modified to reflect Japanese transactional practices.

Revision History: The most current version is JIS G 3193:2025, which replaced the 2019 and 2008 versions. Core Specifications

The standard provides precise tables for dimensions and tolerances, ensuring consistency for manufacturers and engineers. Specification Key Requirements Expression of Size

Plates/sheets are expressed by thickness, width, and length (mm). Strips use thickness and width (mm). Standard Thickness

For steel strips and cut lengths, the standard thickness is generally 12.7 mm or under. Standard Width

For strips and cut lengths, widths are generally 2,000 mm or under. Thickness Tolerances

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 ±0.16 mm. Flatness & Camber

Includes maximum allowable deviations for flatness and lateral warpage (camber) based on width and length. Measurement Guidelines

The standard also specifies where to measure to ensure accuracy:

Mill-Edged Strips: Thickness must be measured at least 25 mm from the side edge.

Cut-Edged Strips: Thickness must be measured at least 15 mm from the side edge.

Strips under 30-50mm width: Measurements are typically taken along the center line. Accessing the PDF

JIS G 3193 is the Japanese Industrial Standard for the dimensions, mass, and permissible variations of hot-rolled steel plates, sheets, and strips. The current version is JIS G 3193:2019, which replaced previous editions like JIS G 3193:2008 and 1990. Core Technical Specifications

This standard defines the requirements for hot-rolled steel products, excluding flat bars. It is based on ISO 7452:2013 with modifications for local transactional practices. HOT ROLLED STEEL SHEET

What is JIS G 3193?

JIS G 3193 is a Japanese Industrial Standard (JIS) that specifies the dimensions, shape, mass, and permissible deviations for hot-rolled steel plates, sheets, and strip.

While standards like JIS G 3101 (General Structural Steel) or JIS G 3106 (Rolled Steel for Welded Structures) dictate the chemical composition and mechanical properties (tensile strength, yield point), JIS G 3193 dictates the physical geometry.

“The PDF is the same as free online summaries.”

No. The official PDF includes legally binding tables, footnotes, and revision history. Summaries omit critical notes like "tolerances apply after removing oxide scale."

What is JIS G 3193?

JIS G 3193 is a Japanese Industrial Standard titled: "Dimensions, shape, mass and permissible variations of hot-rolled steel plates and sheets."

It specifies the standard dimensions, tolerances, and permissible variations for hot-rolled steel plates and sheets produced in Japan. It applies to general structural steels, automotive, shipbuilding, and pressure vessel grades unless otherwise specified in individual product standards (e.g., JIS G 3101, JIS G 3106, JIS G 3116).

⚠️ Warning on Free PDFs

You will find many websites offering a free jis g 3193 pdf download. Most of these are:

  • Outdated (e.g., JIS G 3193:1990 instead of 2019 revision).
  • Poorly scanned and illegible.
  • Non-compliant for legal or audit purposes.

Using an outdated or fake PDF in a contract or QC inspection can lead to rejected shipments or liability. Always buy from JSA or an authorized reseller.

Q2: How does JIS G 3193 compare to ASTM A6/A6M?

A: ASTM A6 is the American standard for general requirements for rolled steel shapes. Both cover similar ground (dimensions, mass, tolerances), but the numbers differ. An H-beam meeting JIS G 3193 may not automatically meet ASTM A6 without conversion. Always specify the governing standard.
