Strong Match — 90.1% match
based on chemical composition and mechanical property overlap.
EN ISO 4957 X40CrMoV5-1 (EN ISO 4957:2018) and ASTM A681 H13 (ASTM A681:2008) are both steel grades.
Both fall under the Tool & Die Steels category.
EN ISO 4957 X40CrMoV5-1 is typically used for die casting dies, extrusion dies, forging dies, hot shear blades, while ASTM A681 H13 is commonly used for die casting dies, extrusion dies, forging dies, hot stamping.
EN ISO 4957 X40CrMoV5-1 is defined under European Standard (EN), originating from Europe, while ASTM A681 H13 is defined under ASTM International, originating from United States.
As per chemical composition, EN ISO 4957 X40CrMoV5-1 vs ASTM A681 H13 is a 85.1% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 90.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
