JIS G3193 is a foundational standard for ensuring quality in hot-rolled steel products. By obtaining the , you empower your technical team to ensure that the material received meets the required dimensions, shapes, and tolerances for safety and structural integrity.
However, this ease of access comes with the responsibility of version control. JIS standards are periodically reviewed and revised to keep pace with manufacturing technologies and international standards like ISO. Relying on an outdated PDF can lead to costly errors. For example, a revision might tighten the tolerance for high-strength steel plates; using an older version of the document could result in accepting non-compliant material.
(for US customers)
A major section of the JIS G3193 standard details how to calculate the theoretical weight of steel shipments. This ensures transactional transparency between steel mills, trading houses, and end-users. The basic formula used for flat steel calculation is: jis g3193 pdf
Many countries have agreements to resell JIS standards. You can purchase the PDF from reputable national bodies in your region, such as:
Size are available from 1.2 mm to 25.4 mm in thickness and from 600 mm to 2180 mm in width. 日本製鉄株式会社
For example, thinner sheets under 3.15 mm have tighter tolerances (often ± 0.16 mm to ± 0.4 mm depending on width).
The standard is a copyrighted document published by the Japanese Standards Association (JSA). : The authoritative version is available for purchase
: Defines standard thicknesses typically ranging from 1.2 mm to 350 mm , depending on the specific product type. Detailed Tolerances : Provides precise tables for: Thickness : Variations based on the width of the plate.
JIS G3193 defines the permissible imperfections on the surface of the steel, such as scales, cracks, or flaws, and dictates the standards for flatness and crown, ensuring the steel is functional for its intended use. Where to Find the JIS G3193 PDF
Having the official document is essential for engineers, quality control inspectors, and purchasing agents to:
The nominal width of the plate (wider plates allow for slightly higher variance due to mill roll deflection). However, this ease of access comes with the
When you download or consult a JIS G3193 PDF, the core value lies in its comprehensive tolerance tables. A. Thickness Tolerances
Thinner flat steel, often supplied in cut lengths.
Understanding where JIS G 3193 fits among global standards is crucial for international trade and engineering.
