Extruded profiles manufactured under the JIS H 4100 standard are rigorously tested to ensure mechanical and dimensional compliance. The document organizes profiles into and Special Class designations, which dictate the strictness of the dimensional tolerances. 1. Common Alloy Grades and Applications
Applies to all cross-sections not already covered under JIS H 4040 (rods, bars) and JIS H 4080 (tubes). For quadrangular, rectangular, or hexagonal cross-sections, it applies specifically to profiles where corner radii are defined. jis h4100 standard pdf
First established on May 1, 1970, and updated in its most recent revision— JIS H 4100:2022 —this standard ensures that extruded profiles meet strict criteria regarding chemical composition, mechanical properties, and dimensional tolerances.
