Use the given cross-sectional area (cm²) multiplied by steel density (7.85 g/cm³) and length. The PDF provides precalculated kg/m values for common sizes—check them against your own calculation.
Provides a common technical basis for buyers and suppliers. Updates and International Harmonization
Usually +30 mm / -0 mm, although tighter tolerances can be requested. D. Flatness Tolerances (Shape)
The standard meticulously details permissible variations in:
To ensure that the mill produces steel to your exact dimensional constraints, you must cite the exact clause from the standard. 5. Summary Table: Typical Tolerance Coverage Key Factors Key Takeaway from JIS G 3193 Thickness Nominal thickness (t) Stricter for thinner material, looser for thick plates. Width Edge type (Mill vs. Cut) Cut edges have higher accuracy (+ tolerances). Length Ordered length Mostly positive tolerance (+ Length / -0). Flatness Yield Strength & t Specific limits for wave/buckle based on grade. 6. How to Locate and Use JIS G 3193 jis g 3193 pdf
If you are downloading a , it is vital to ensure you are using the most current version.
While standards like (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.
By establishing uniformity in these categories, JIS G 3193 ensures that a designer in Tokyo can specify a steel plate and a fabricator in Osaka—or indeed, anywhere in the world adhering to JIS—knows exactly what dimensions and tolerances to expect.
The standard applies to hot-rolled steel plates, sheets (including those cut from strips), and strips, but specifically . Use the given cross-sectional area (cm²) multiplied by
Searching for "JIS G 3193 PDF" is often driven by the need for specific lookup tables. Here is a preview of the most requested data categories inside the document:
Beyond dimensions, JIS G 3193 dictates limits on shape imperfections, primarily (or crown/camber), ensuring that plates and sheets lie flat for processing. 3. Mass Calculation
Thickness is one of the most critical factors and is measured at specific locations depending on the edge type (e.g., at least 25mm from the edge for mill-edged strips). Width (mm) Thickness (mm) Tolerance (mm) Under 1,600 Under 1.25 Under 1,600 1.60 to (Data sourced from JIS G 3193 Table 4 ). 2. Shape and Flatness
A common point of confusion is the relationship between JIS G 3193, JIS G 3101, and the famous SS400 grade. Updates and International Harmonization Usually +30 mm /
Lists other standards required for the application of JIS G 3193.
The standard provides a uniform framework for measuring and certifying the physical properties of hot-rolled steel. Unlike other JIS standards (such as ), which focus on chemical composition and mechanical strength, JIS G 3193 specifically targets geometrical accuracy and tolerances .
: Flat pieces sheared directly from coils, which carry unique processing tolerances distinct from standalone plates. Structural Exclusions
is the Japanese Industrial Standard that defines the dimensions, shape, mass, and permissible variations for hot-rolled steel plates, sheets, and strips.
