Flatness is crucial for welding and fabrication. JIS G 3193 provides limits for wave or buckle height based on the steel’s yield strength and thickness. The standard generally allows lower tolerances for high-yield steel and thicker plates. 4. Why You Need the "JIS G 3193 PDF" Official Document

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:

Usually allow strict tolerances between ±0.20 mm and ±0.35 mm depending on width. jis g 3193 pdf

The standard does not apply to flat bars, and its application is ultimately defined in the relevant product-specific standards that reference JIS G 3193.

This standard is essential for manufacturers, quality control professionals, engineers, and anyone involved in specifying, procuring, or working with hot-rolled steel plates, sheets, and strips in the Japanese market and beyond. Its precise tolerances and clear guidelines support the production of high-quality products and facilitate smooth international trade. Flatness is crucial for welding and fabrication

Thickness deviation is the most tightly regulated aspect of JIS G 3193. The allowable variance increases as the nominal thickness and width of the plate increase.

It is important to distinguish between "unofficial" mirrors and the authoritative source. While you may find scanned copies on engineering forums, these are often:

The JIS G 3193 standard regulates the production profile of dimensional boundaries across three fundamental structural shapes:
