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.

Scope of JIS G3193: JIS G3193 applies to hot-rolled steel plates used in shipbuilding, including plates for hull construction, superstructures, and other shipbuilding applications. The standard covers steel plates with thicknesses ranging from 5 mm to 100 mm and widths ranging from 600 mm to 3000 mm.

Key Requirements: The JIS G3193 standard outlines several key requirements for hot-rolled steel plates used in shipbuilding, including:

  1. Chemical Composition: The standard specifies the chemical composition of steel plates, including limits on carbon, manganese, silicon, and other elements.
  2. Mechanical Properties: The standard requires steel plates to meet specific mechanical properties, such as tensile strength, yield strength, and elongation.
  3. Testing and Inspection: The standard outlines the testing and inspection requirements for steel plates, including tensile testing, impact testing, and ultrasonic testing.
  4. Surface Quality: The standard specifies the surface quality requirements for steel plates, including limits on surface defects and imperfections.

Significance of JIS G3193: The JIS G3193 standard plays a crucial role in ensuring the quality and safety of shipbuilding materials. By specifying the technical conditions for the production, testing, and inspection of steel plates, the standard helps to:

  1. Ensure Safety: By ensuring that steel plates meet specific mechanical properties and surface quality requirements, the standard helps to prevent accidents and ensure the safety of ships and their crew.
  2. Promote Quality: The standard promotes quality in shipbuilding by specifying the requirements for steel plates and ensuring that they are met.
  3. Facilitate International Trade: The standard facilitates international trade by providing a common set of requirements for steel plates used in shipbuilding.

Conclusion: In conclusion, JIS G3193 is an important standard that specifies the requirements for hot-rolled steel plates used in shipbuilding. The standard's key requirements, including chemical composition, mechanical properties, testing and inspection, and surface quality, help to ensure the quality and safety of shipbuilding materials. As the shipbuilding industry continues to evolve, the JIS G3193 standard will remain a critical component in ensuring the safety and performance of ships.

If you're sourcing steel internationally, you've likely seen JIS G 3193:2019 . But how does it compare? While similar to ISO 7452:2013

, JIS G 3193 includes specific technical modifications to reflect Japanese transaction practices . For those used to standards, it’s comparable to specifications like for general tolerances of structural steel Key Data Points in the Standard: Thickness Tolerances:

Varies based on width; for example, plates under 1600mm wide have tighter +/- tolerances than wider products Measurement Zones:

Thickness must be measured at least 15mm from the edge for cut-edged plates, or 25mm for mill-edged strips Working on an international bid?

JIS G 3193 standard specifies the dimensions, mass, and permissible variations (tolerances) for hot-rolled steel plates, sheets, and strips

. It is the primary reference for manufacturing and quality control of flat-rolled steel in Japan and is widely used across the global supply chain 📋 Key Specifications

The standard covers three main categories of flat steel products: Steel Plates and Sheets : Defined by thickness, width, and length Steel Strips : Defined by thickness and width (often supplied in coils) Cut Lengths : Strips that have been cut into specific sheet lengths : This standard specifically does apply to flat bars 📏 Dimensional Tolerances

Tolerances vary based on the thickness and width of the material. Below is a summary of standard thickness tolerances for common dimensions: Thickness Tolerances (Typical Values) Specified Thickness (mm) Width < 1600mm Width 1600–2000mm Width 2000–2500mm Under 1.25 plus or minus 0.16 1.60 to < 2.00 plus or minus 0.19 3.15 to < 4.00 plus or minus 0.24 plus or minus 0.34 plus or minus 0.34 10.0 to < 16.0 plus or minus 0.55 plus or minus 0.65 plus or minus 0.65 Measurement Rules Mill Edges : Thickness must be measured at least from the side edge : Thickness must be measured at least from the side edge 🛠 Comparison & Compliance International Equivalent : JIS G 3193 is a modified version ( ISO 7452:2013

JIS G 3193:2019 is the primary Japanese Industrial Standard that specifies the dimensions, mass, and permissible variations (tolerances) for hot-rolled steel plates, sheets, and strips.

Unlike many other JIS standards that define the chemical composition or mechanical properties of a specific metal (like JIS G 3101 for general structures), G 3193 is a dimensional standard. It is used as a companion to multiple product standards to ensure that hot-rolled steel meets strict geometric requirements. 1. Scope and Application

This standard applies to hot-rolled steel products manufactured in Japanese mills, specifically:

Steel Plates: Generally thicker sections used in heavy construction. Steel Sheets: Thinner flat products. Steel Strips: Coiled hot-rolled steel. Significance of JIS G3193: The JIS G3193 standard

Exclusions: It explicitly does not apply to flat steel bars. 2. Core Dimensional Tolerances

The standard provides detailed tables for permissible variations based on the size and shape of the steel.

Thickness Tolerances: Measured at specific distances from the edge—typically at least 25 mm for mill-edged strips and 15 mm for cut-edged plates. The tolerance varies depending on the nominal width and thickness.

Width and Length Tolerances: Variations allowed depend on whether the edges are mill-rolled or cut/trimmed.

Shape and Flatness: The standard defines "lateral warpage" (camber) and flatness limits to ensure the material remains usable for fabrication. 3. Measuring and Calculation

Mass Calculation: JIS G 3193 provides the formula for calculating the theoretical mass of steel based on its nominal dimensions.

Appearance: Specifies that the steel must be free from defects that are detrimental to practical use, although surface imperfections typical of hot-rolling are generally acceptable. 4. Technical Revision History

The standard is periodically reviewed to align with modern manufacturing capabilities. Current Version: JIS G 3193:2019. Superseded Versions: 2008, 2005, and 1990. JIS G 3193-2019 PDF (Dung Sai Thep Tam) - Scribd
