| Standard | Title | Focus | |----------|----------------|--------------------------------| | | Hot-rolled plates & sheets | Flat products (plates, sheets, coils) | | JIS G 3192 | Hot-rolled steel sections | Shapes: angles, channels, I-beams | | JIS G 3194 | Hot-rolled steel bars | Round, square, hexagonal bars |
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
Accessing the official PDF version of this standard is essential for several industrial workflows: Quality Assurance (QA) and Inspections
Usually allow strict tolerances between ±0.20 mm and ±0.35 mm depending on width. jis g 3193 pdf
with specific technical modifications to align with Japanese transactional practices. 1. Scope and Application This standard defines the requirements for: Hot Rolled Steel Plates: Large, flat steel products with specific thickness. Steel Sheets: Including cut lengths from steel strips. Steel Strips: Continuous coils of hot rolled steel.
You will find many websites offering a free download. Most of these are:
For extreme dimensions (e.g., thickness over 40 mm or widths exceeding 5,000 mm), tolerances may be moderated through direct agreement between the purchaser and supplier. Where to Find the PDF JIS G 3193-2019 PDF (Dung Sai Thep Tam) - Scribd Thickness Tolerances : Requirements for flatness
For compliance and accuracy, always purchase the official JIS G 3193 PDF from the Japanese Standards Association (JSA) Web Store or an authorized distributor. Avoid "free" versions which are often outdated and incomplete.
Thickness variation is the most heavily scrutinized metric in steel manufacturing. JIS G 3193 categorizes thickness tolerances based on two primary factors:
Tip: If you are working for a large engineering firm, check your company’s internal digital library. Most major firms hold enterprise licenses for these standards. and surface quality.
For example, an engineer might specify a beam using the designation (defined in JIS G 3101), which dictates the steel must have a tensile strength of 400–510 MPa. However, if that engineer needs to know the exact thickness tolerance or the theoretical weight per meter of that SS400 plate, they must consult JIS G 3193 . This separation of duties—mechanical properties versus dimensional properties—is a hallmark of the JIS system and allows for greater flexibility in manufacturing.
No. It covers only hot-rolled flat products. Cold-rolled sheets follow JIS G 3141. Sections follow JIS G 3192.
The core value of the lies in its definitive reference tables. The standard ensures that steel manufactured by major global mills meets predictable dimensional boundaries. 1. Thickness Tolerances
