Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 3748 T105Cr5Mn2 (IS 3748:1990) and GOST 5950 3H2W8F (GOST 5950-2000) are both steel grades.
Both fall under the Tool & Die Steels category.
IS 3748 T105Cr5Mn2 is typically used for cold work tools and dies for blanking, trimming, chipping and shearing, while GOST 5950 3H2W8F is commonly used for used for forging dies, extrusion tools, hot punches, mandrels, and die inserts..
IS 3748 T105Cr5Mn2 is defined under Bureau of Indian Standards (IS) (India).
As per chemical composition, IS 3748 T105Cr5Mn2 vs GOST 5950 3H2W8F is a 59.9% 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.
