Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
JIS G4404 SKS93 (JIS G4404:2006) and GOST 5950 3H2W8F (GOST 5950-2000) are both steel grades.
Both fall under the Tool & Die Steels category.
JIS G4404 SKS93 is typically used for cold working molds, press dies, blanking dies, shear blades, gauges, jigs., while GOST 5950 3H2W8F is commonly used for used for forging dies, extrusion tools, hot punches, mandrels, and die inserts..
JIS G4404 SKS93 is defined under Japanese Industrial Standards (JIS) (Japan).
As per chemical composition, JIS G4404 SKS93 vs GOST 5950 3H2W8F is a 60.5% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
Used for forging dies, extrusion tools, hot punches, mandrels, and die inserts.
Key Differences
JIS G4404 SKS93 specifies Mn, P, S which are not specified for GOST 5950 3H2W8F.
