Minimal Match — 41.7% match
based on chemical composition and mechanical property overlap.
JIS G4404 SKD11 (JIS G4404:2006) and GOST 5950 4H5MFS1 (GOST 5950-2000) 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 GOST 5950 4H5MFS1 is commonly used for used for forging dies, pressure casting dies, hot punches, extrusion tooling, and die inserts..
JIS G4404 SKD11 is defined under Japanese Industrial Standards (JIS) (Japan).
As per chemical composition, JIS G4404 SKD11 vs GOST 5950 4H5MFS1 is a 62.6% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 41.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
Used for forging dies, pressure casting dies, hot punches, extrusion tooling, and die inserts.
Key Differences
JIS G4404 SKD11 specifies Mn which is not specified for GOST 5950 4H5MFS1.
Can JIS G4404 SKD11 Be Substituted With GOST 5950 4H5MFS1?
JIS G4404 SKD11 and GOST 5950 4H5MFS1 share some compositional similarity but differ enough that substitution should not be assumed. Review the differences above carefully, and consult the applicable standard or a metallurgist before using one in place of the other.
