Close Alternative — 81.6% match
based on chemical composition and mechanical property overlap.
EN ISO 683-17 20CrMo4 (EN ISO 683-17:2014) and SAE J404 4135 (SAE J404:2000) are both steel grades.
Both fall under the Alloy Steel category.
EN ISO 683-17 20CrMo4 is typically used for used in gears, shafts, axles, high-tensile bolts, and structural components., while SAE J404 4135 is commonly used for chemistry-only alloy steel grade; see the composition notes for product scope.
EN ISO 683-17 20CrMo4 is defined under European Standard (EN), originating from Europe, while SAE J404 4135 is defined under SAE International, originating from United States.
As per chemical composition, EN ISO 683-17 20CrMo4 vs SAE J404 4135 is a 81.6% 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 81.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
