Close Alternative — 75.4% match
based on chemical composition and mechanical property overlap.
EN 10083-3 33MnCrB5-2 (EN 10083-3:2006) and SAE J404 5132 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
EN 10083-3 33MnCrB5-2 is typically used for quenched and tempered, flame or induction hardened machine parts (clause 1), while SAE J404 5132 is commonly used for high-tensile bolts, studs, shafts and engineering components requiring surface hardness.
EN 10083-3 33MnCrB5-2 is defined under European Standard (EN), originating from Europe, while SAE J404 5132 is defined under SAE International, originating from United States.
As per chemical composition, EN 10083-3 33MnCrB5-2 vs SAE J404 5132 is a 75.4% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 75.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
