Full title and description
St JIS G 4052-2016 — Structural steels with specified hardenability bands. This Japanese Industrial Standard specifies steels intended primarily for machine-structural use where specified hardenability bands are required; it covers products manufactured by hot rolling, hot forging and hot extruding and intended for further machining, forging or heat treatment. This standard excludes steel tubes.
Abstract
JIS G 4052:2016 defines classification, symbols, manufacturing methods, chemical composition limits, quality requirements, dimensional and appearance criteria, tests, inspection, marking and reporting for structural steels supplied with specified hardenability bands. Annexes include requirements for hot‑extruded sections and a comparison table to corresponding international standards (for example ISO 683 series).

Scope
This standard applies to structural steel products with a uniform cross‑section that are manufactured by hot rolling, hot forging or hot extruding and are supplied for use after additional processing such as forging, cutting or heat treatment. The standard specifies required hardenability bands and associated chemical, mechanical and dimensional requirements; it explicitly excludes steel tubes. The manufacturing method and quality requirements for hot‑extruded sections are provided in an annex.
Key topics and requirements
- Classification and symbol system for steels with designated hardenability bands.
- Permitted manufacturing methods: hot rolling, hot forging and hot extruding (with annexed requirements for extrusions).
- Chemical composition limits for specified grades targeted at required hardenability.
- Quality and mechanical property requirements, including heat‑treatable and quench/tempering considerations.
- Appearance, shape, dimensional tolerances and notation of uniform cross‑section products.
- Required tests, inspection procedures, marking and reporting requirements for supplied material.
- Informative comparison to related ISO standards (e.g., ISO 683 series) to indicate degree of correspondence.
Typical use and users
Used by steel producers, heat‑treatment shops, machine and component manufacturers, materials engineers, quality and procurement teams, testing laboratories and certification bodies that require standardized specifications for steels where controlled hardenability is important (e.g., shafts, gears, pins and other quenched/tempered machine components).
Related standards
This 2016 edition superseded earlier JIS publications (including prior versions of JIS G 4052 and related JIS G 7501 / JIS G 7503 material). The 2016 edition itself has been superseded by JIS G 4052:2023. The standard references and compares to international standards such as ISO 683‑2 and ISO 683‑3 where applicable.

FAQ
Q: What is this standard?
A: JIS G 4052:2016 is a Japanese Industrial Standard that defines requirements for structural steels supplied with specified hardenability bands for machine‑structural use.
Q: What does it cover?
A: It covers classification, manufacturing methods (hot rolling, forging, extruding), chemical composition limits, quality and mechanical requirements, dimensional and appearance tolerances, tests, inspection, marking and reporting for uniform cross‑section steel products (excluding tubes). Annexes address hot‑extruded section requirements and comparisons to international standards.
Q: Who typically uses it?
A: Steel mills, component manufacturers, heat‑treaters, design and materials engineers, procurement and quality assurance teams, and testing/inspection laboratories that work with quenched-and‑tempered or otherwise heat‑treated machine steels.
Q: Is it current or superseded?
A: The 2016 edition is superseded; a newer edition, JIS G 4052:2023, replaces JIS G 4052:2016 (supersession recorded in 2023). For current requirements and any technical changes, refer to the 2023 edition.
Q: Is it part of a series?
A: It forms part of the JIS G series of standards covering steels and related products and cross‑references international standards on heat‑treatable and case‑hardening steels (for example ISO 683 parts). It also relates to earlier JIS documents on steel grades and manufacturing methods that were consolidated or superseded.
Q: What are the key keywords?
A: Hardenability, structural steel, hot rolling, hot forging, hot extruding, chemical composition, heat treatment, dimensional tolerances, inspection, JIS G 4052.
