JIS Standard List: Iron, Structural and Constructional Steels, Stainless Steels and Coated Steels

---

Development and Scope of JIS Standards

The Japanese Industrial Standards Committee (JISC), headquartered in Tokyo, develops and maintains the JIS standards as part of Japan's comprehensive industrial standardization initiative. These standards serve as the cornerstone of quality control and product specification across various industrial sectors.

Material Categories

The JIS standards system encompasses four primary material categories:

1.   Iron
2.   Structural and Constructional Steels
3.   Stainless Steels
4.   Coated Steels

Each category features detailed specifications tailored to specific industrial applications and requirements. For a comprehensive understanding of the classification system, readers can refer to the Introduction to the JIS Standard Designation System.

Key Industrial Applications

The standards address diverse industrial needs, with notable applications including:

• Automotive Manufacturing: Specifications for hot-rolled sheets, strips, and plates engineered specifically for automobile production
• Water Infrastructure: Detailed standards for coated steel pipework systems, ensuring reliability in water distribution networks
• Precision Engineering: Guidelines for stainless steel strips and wires used in spring production, meeting exact tolerances and performance requirements

This structured approach ensures consistent quality and reliability across various industrial applications while facilitating international trade and standardization efforts.
