Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
JIS G4404 SKS31 (JIS G4404:2006) and IS 3748 103T3 (IS 3748:1990) are both steel grades.
Both fall under the Tool & Die Steels category.
JIS G4404 SKS31 is typically used for cold working molds, press dies, jigs, gauges, long taps, reamers, measuring tools requiring minimal quenching distortion., while IS 3748 103T3 is commonly used for cold work tools and dies for blanking, trimming, chipping and shearing.
JIS G4404 SKS31 is defined under Japanese Industrial Standards (JIS), originating from Japan, while IS 3748 103T3 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, JIS G4404 SKS31 vs IS 3748 103T3 is a 72.6% 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.
