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

Thickness deviation is tightly regulated based on both nominal thickness and the overall width of the plate. As width increases, the allowable variation slightly expands to accommodate normal deflection during the hot-rolling process. A generalized breakdown of standard tolerances includes: Nominal Thickness Range (mm) Tolerance For Widths Under 1,600 mm Tolerance For Widths 1,600 mm to 2,000 mm ±plus or minus ±plus or minus 3.15 to Under 4.00 ±plus or minus ±plus or minus 6.00 to Under 10.00 ±plus or minus ±plus or minus 16.0 to Under 25.0 ±plus or minus ±plus or minus 25.0 to Under 40.0 ±plus or minus ±plus or minus jis g 3193 pdf

These revisions demonstrate the Japanese Standards Association's commitment to ensuring that JIS G 3193 remains relevant, precise, and aligned with the needs of the modern steel industry.

It serves as a dimensional reference for other product-specific standards (e.g., JIS G 3101 for general structural steel or JIS G 3106 for welded structures). International Alignment: Modified based on ISO 7452:2013 to better reflect regional transactional practices. Key Technical Sections JIS G 3193-2019 PDF (Dung Sai Thep Tam) - Scribd

JIS G 3193:2019 Japanese Industrial Standard (JIS) that specifies the dimensions, shape, mass, and permissible variations of hot-rolled steel plates, sheets, and strips The most current version is JIS G 3193:2025

| Nominal Thickness (mm) | Tolerance for Width < 1600 mm | Tolerance for 1600-2000 mm | |------------------------|-------------------------------|-----------------------------| | 1.5 to 3.0 | ±0.20 mm | ±0.22 mm | | Over 3.0 to 6.0 | ±0.22 mm | ±0.35 mm | | Over 6.0 to 10.0 | ±0.35 mm | ±0.50 mm | | Over 10.0 to 16.0 | ±0.50 mm | ±0.70 mm | | Over 16.0 to 25.0 | ±0.70 mm | ±1.00 mm |

For cut plates and sheets, lengths are given exclusively in positive variations (e.g., over nominal, under) to eliminate shortages during field cutting. 3. Flatness and Lateral Warpage

Standard cut-length tolerances typically range from depending on the total length of the plate. 4. Flatness and Camber It serves as a dimensional reference for other

The standard applies to a wide range of hot-rolled steel products, including:

Unlike specific material property standards like JIS G 3101 (structural steel) or JIS G 3106 (welded structures), . It is referenced by these material standards to define what constitutes an acceptable tolerance for thickness, flatness, width, and length. What is covered under JIS G 3193?

Features wider tolerances (often +25 mm / -0 mm) because the edges are not trimmed after rolling.

JIS G 3193 is a dimensional standard. Unlike material standards such as JIS G 3101 (SS400) or JIS G 3106 (SM490), which dictate chemical composition and mechanical properties, JIS G 3193 defines physical limits. It specifies exactly how thick, wide, long, and flat a hot-rolled steel product can be. Scope of the Standard
