Strong Match — 93.7% match
based on chemical composition and mechanical property overlap.
DIN 17200 30CrMo4 (DIN 17200:1986) and SAE J404 4130 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
DIN 17200 30CrMo4 is typically used for high tensile tubes, pressure vessels, aircraft structures, while SAE J404 4130 is commonly used for aircraft structures, pressure vessels, high tensile tubes.
DIN 17200 30CrMo4 is defined under Deutsches Institut fur Normung (DIN), originating from Germany, while SAE J404 4130 is defined under SAE International, originating from United States.
As per chemical composition, DIN 17200 30CrMo4 vs SAE J404 4130 is a 93.7% 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 93.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
