Close Alternative — 79% match
based on chemical composition and mechanical property overlap.
JIS G4404 SKD11 (JIS G4404:2006) and EN ISO 4957 X155CrVMo12-1 (EN ISO 4957:2018) are both steel grades.
Both fall under the Tool & Die Steels category.
JIS G4404 SKD11 is typically used for precision blanking dies, cold forming tools, gauges, while EN ISO 4957 X155CrVMo12-1 is commonly used for blanking dies, forming dies, thread rolling dies, gauges.
JIS G4404 SKD11 is defined under Japanese Industrial Standards (JIS), originating from Japan, while EN ISO 4957 X155CrVMo12-1 is defined under European Standard (EN), originating from Europe.
As per chemical composition, JIS G4404 SKD11 vs EN ISO 4957 X155CrVMo12-1 is a 68.5% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a close alternative overall at 79%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
