Strong Match — 89.1% match
based on chemical composition and mechanical property overlap.
SS 14 21 72 2172 and SAE J403 1045 (SAE J403:2009) are both steel grades.
Both fall under the Carbon Steel category.
SS 14 21 72 2172 is typically used for shafts,axles,gears,studs,bolts,general engineering components,machine parts, while SAE J403 1045 is commonly used for chemistry-only grade; product scope as listed in the composition notes.
SS 14 21 72 2172 is defined under Swedish Standards (SS), originating from Sweden, while SAE J403 1045 is defined under SAE International, originating from United States.
As per chemical composition, SS 14 21 72 2172 vs SAE J403 1045 is a 89.1% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 89.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
