Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
JIS G4804 SUM22 (JIS G 4804:2021) and SAE J403 1126 (SAE J403:2014) are both steel grades.
Both fall under the Free Machining Steel category.
JIS G4804 SUM22 is typically used for screw machine parts, bolts, studs, pins, while SAE J403 1126 is commonly used for chemistry-only grade; product scope as listed in the composition notes.
JIS G4804 SUM22 is defined under Japanese Industrial Standards (JIS), originating from Japan, while SAE J403 1126 is defined under SAE International, originating from United States.
As per chemical composition, JIS G4804 SUM22 vs SAE J403 1126 is a 80.5% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
