Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
GB/T 1299 Cr12 (GB/T 1299-2014) and IS 1570 (Part 6) T105Cr5Mn2 (IS 1570 (Part 6):1996) are both steel grades.
Both fall under the Tool & Die Steels category.
GB/T 1299 Cr12 is defined under Guobiao Standards (GB/T), originating from China, while IS 1570 (Part 6) T105Cr5Mn2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, GB/T 1299 Cr12 vs IS 1570 (Part 6) T105Cr5Mn2 is a 71.4% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
