Jis G 3193 Pdf
It explicitly does not apply to flat bars or specialized structural sections, which fall under standards like JIS G 3192 . 📏 Technical Overview: Standard Dimensions & Tolerances
To ensure that the mill produces steel to your exact dimensional constraints, you must cite the exact clause from the standard. 5. Summary Table: Typical Tolerance Coverage Key Factors Key Takeaway from JIS G 3193 Thickness Nominal thickness (t) Stricter for thinner material, looser for thick plates. Width Edge type (Mill vs. Cut) Cut edges have higher accuracy (+ tolerances). Length Ordered length Mostly positive tolerance (+ Length / -0). Flatness Yield Strength & t Specific limits for wave/buckle based on grade. 6. How to Locate and Use JIS G 3193
The is the foundational manufacturing benchmark governing the dimensions, shapes, masses, and permissible variations of hot-rolled steel plates, sheets, and strips . Published by the Japanese Standards Association (JSA), this document does not outline chemical or mechanical properties. Instead, it acts as a universal dimensional blueprint referenced by dozens of material-specific standards like JIS G 3101 (general structures) or JIS G 3113 (automobile structural usage). Understanding the geometric constraints of a JIS G 3193 PDF is crucial for engineers, procurement managers, and fabricators to ensure structural integrity and minimize material waste. 1. Scope and Technical Core of JIS G 3193 jis g 3193 pdf
The standard ensures that the actual thickness, width, length, and flatness of the steel produced conform within acceptable limits to the ordered dimensions.
The standard, titled "Dimensions, shape, mass and permissible variations of hot rolled steel plates, sheets and strips" , is a fundamental Japanese industrial specification that defines the physical requirements for hot-rolled steel products. It is widely used in global manufacturing to ensure consistency in the dimensions and surface quality of steel used in construction, automotive parts, and machinery. 1. Scope and Core Purpose It explicitly does not apply to flat bars
The 2019 revision introduced changes regarding the definition of "strip" and updated tolerance tables to align more closely with international standards (like ISO 4995). Using an outdated PDF could lead to non-compliant fabrication or rejected material shipments.
For strips and cut lengths, widths are generally . Thickness Tolerances Summary Table: Typical Tolerance Coverage Key Factors Key
Evaluated by placing the plate on a level surface and measuring the maximum peak-to-valley distance per unit length. 🌐 Global Alignment: JIS G 3193 vs. ISO 7452
The core of the document is defining how accurate the hot-rolled material must be. The tolerances are generally categorized by the product's thickness and width. A. Thickness Tolerances
Modern iterations of this standard—including and the latest JIS G 3193:2025 revisions—harmonize extensively with international standards.
The 2019 edition is technically modified from ISO 7452:2013 to better align with Japanese market practices.
