Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 6) T90V2 (IS 1570 (Part 6):1996) and GB/T 1299 4Cr5MoSiV1 (GB/T 1299-2014) are both steel grades.
Both fall under the Tool & Die Steels category.
IS 1570 (Part 6) T90V2 is defined under Bureau of Indian Standards (IS), originating from India, while GB/T 1299 4Cr5MoSiV1 is defined under Guobiao Standards (GB/T), originating from China.
As per chemical composition, IS 1570 (Part 6) T90V2 vs GB/T 1299 4Cr5MoSiV1 is a 60% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
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.
