Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
SAE J404 52100 (SAE J404:2009) and GOST 4543 12HN3A (GOST 4543-2016) are both steel grades.
Both fall under the Alloy Steel category.
SAE J404 52100 is typically used for ball bearings, roller bearings, races, bushings, precision tooling, dies, gauges, while GOST 4543 12HN3A is commonly used for used for gears, pinions, crankshafts, aircraft parts, and transmission components..
SAE J404 52100 is defined under SAE International (United States).
As per chemical composition, SAE J404 52100 vs GOST 4543 12HN3A is a 67.1% 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.
Used for gears, pinions, crankshafts, aircraft parts, and transmission components.
