Strong Match — 91.5% match
based on chemical composition and mechanical property overlap.
EN ISO 4957 X38CrMoV5-1 (EN ISO 4957:2018) and BS 4659 BH13 (BS 4659:1989) are both steel grades.
Both fall under the Tool & Die Steels category.
EN ISO 4957 X38CrMoV5-1 is typically used for die casting dies, extrusion tooling, forging dies, while BS 4659 BH13 is commonly used for die casting dies, forging tools, extrusion dies.
EN ISO 4957 X38CrMoV5-1 is defined under European Standard (EN), originating from Europe, while BS 4659 BH13 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN ISO 4957 X38CrMoV5-1 vs BS 4659 BH13 is a 87.2% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 91.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
