If a buyer receives a shipment of steel sheets that are slightly wavy or narrower than specified, JIS G 3193 acts as the legal arbiter. If the variance falls outside the standard's tables, the shipment is classified as non-compliant reject material. Summary of Common Companion Standards
JIS G 3193 provides the standard method for calculating the theoretical mass of steel sheets. This is vital for:
It is important to distinguish between "unofficial" mirrors and the authoritative source. While you may find scanned copies on engineering forums, these are often: jis g 3193 pdf
. It is a foundational dimensional standard used in conjunction with specific product standards, such as JIS G 3101 for general structures. Store Thí Nghiệm Core Standard Overview
The heart of the JIS G 3193 standard lies in its detailed tables and specifications for dimensions and tolerances. Here is a breakdown of its key provisions. If a buyer receives a shipment of steel
It specifies the standard dimensions, tolerances, and permissible variations for hot-rolled steel plates and sheets produced in Japan. It applies to general structural steels, automotive, shipbuilding, and pressure vessel grades unless otherwise specified in individual product standards (e.g., JIS G 3101, JIS G 3106, JIS G 3116).
A key aspect is the flatness tolerance. For this product, with both width and length under 2000 mm and a thickness of 80 mm (which falls in the 80 mm to 150 mm range), the permitted flatness is 8 mm according to the relevant table. This is vital for: It is important to
Note: The following are generalizations. Always refer to the actual tables for precise procurement. Application Key Constraint Thickness Deviations are tighter for thinner materials ( Width Standard Width Tolerance A (or B) applies. Length Sheared Length ±plus or minus tolerances defined based on plate thickness. Flatness Limits warping based on thickness/width ratio. Why Adhering to JIS G 3193 is Important Using the JIS G 3193 standard is essential for:
When downloading a , ensure the cover page says "JIS G 3193:2019" (or the latest year).
Ensures that structural designs are within authorized tolerance limits.
Accessing the official PDF version of this standard is essential for several industrial workflows: Quality Assurance (QA) and Inspections
