Rolled steels for welded structures (Grades like SM400, SM490).

Applies only to plates and sheets; strips do not have length tolerances as they are sold in coils.

A significant aspect of JIS G 3193 is its methodology for calculating the theoretical mass of steel products. In the steel industry, payment is often made based on weight rather than volume. The standard provides a specific density coefficient (usually 7.85 g/cm³ for carbon steel) and rounding rules for calculating the theoretical weight of a plate based on its dimensions. This standardization eliminates disputes between buyers and sellers regarding the quantity delivered. By adhering to the calculation methods prescribed in the standard, stakeholders can align their procurement audits and inventory management systems. jis g3193 pdf

The standard provides comprehensive tables and rules for the following:

Now, the most common question:

: Outlines limits for camber (lateral warpage), flatness , and out-of-square . Flatness measurements are typically made on a flat surface plate, excluding stretcher-leveled sheets.

These are broken down into categories (e.g., under 3mm, 3mm to 10mm, over 10mm). Rolled steels for welded structures (Grades like SM400,

It is modified from ISO 7452:2013 to reflect Japanese transactional practices. 2. Key Dimensional Measurements Dimensions are strictly expressed in millimetres (mm) : Plates and Sheets: Expressed as Thickness Strips: Expressed as Thickness 3. Standard Thicknesses Standard thickness values range from 1.2 mm to 50 mm .
