Jis G3193 Pdf

Thickness tolerances are strict to ensure uniformity, generally based on the nominal thickness and the width of the plate or strip.

Note: This standard explicitly excludes flat steel bars (which are instead governed by JIS G 3192). Standard Dimensions

Understanding JIS G3193: The Standard for Steel Plates, Sheets, and Strips

Title: JIS G 3193 vs. Global Standards: What You Need to Know jis g3193 pdf

JIS G3193 also covers the permissible crown and flatness of plates and sheets to prevent "waviness" or bowing, which is crucial for structural applications. 3. Why Access the JIS G3193 PDF?

Searching for is the first step, but it is not the last. To ensure quality and legality:

When sourcing hot-rolled steel plates, sheets, or strips, particularly for projects involving Japanese materials, the standard is crucial. It defines the mandatory requirements for dimensions, mass, and permissible variations (tolerances) for these materials.

The standard specifies requirements for the dimensions, mass, shape, and permissible variations (tolerances) of hot-rolled steel plates, sheets, and strips . Always refer to the official Japanese Standards Association

If you need to verify specific tolerances for a project, consulting the 2019 edition of JIS G 3193 on JSA Webdesk is recommended.

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

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.

Specifies the maximum allowable waviness or distortion across the surface of a plate. High flatness is vital for laser cutting and precision machining. Scope and Product Categorization

: Accurate mass calculations help procurement teams estimate shipping costs and material pricing.

It is important to note that JIS G3193 does specify chemical composition or mechanical properties. Instead, it works alongside material standards (such as JIS G3101, G3131, or G3132) to define the physical characteristics of the final product.

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 .

Defines the greatest deviation of a side edge from a straight line. Controlling camber ensures that steel strips feed straight into roll-forming machines. 3. How to Calculate Mass Using JIS G3193

Unlike other standards that define the chemical composition or mechanical properties of steel (such as tensile strength or yield point), JIS G3193 focuses strictly on . It acts as a companion standard. For example, a structural steel grade specified under JIS G3101 (like SS400) or a boiler steel grade under JIS G3103 will use JIS G3193 to determine its allowable thickness, width, length, flatness, and weight tolerances.
