Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
AISI D2 KNL (ASTM A681) and IS 3748 103T3 (IS 3748:1990) are both steel grades.
Both fall under the Tool & Die Steels category.
AISI D2 KNL is typically used for blanking dies, forming dies, thread rolling dies, punches, shear blades, gauges, broaches, drawing dies, while IS 3748 103T3 is commonly used for cold work tools and dies for blanking, trimming, chipping and shearing.
AISI D2 KNL is defined under AISI, originating from United States, while IS 3748 103T3 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, AISI D2 KNL vs IS 3748 103T3 is a 63.9% 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.
