Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 6) T30Ni16Cr5 (IS 1570 (Part 6):1996) and GOST 5950 4H5MFS (GOST 5950-2000) are both steel grades.
Both fall under the Tool & Die Steels category.
IS 1570 (Part 6) T30Ni16Cr5 is defined under Bureau of Indian Standards (IS) (India).
As per chemical composition, IS 1570 (Part 6) T30Ni16Cr5 vs GOST 5950 4H5MFS is a 49.7% 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%.
Frequently Compared With IS 1570 (Part 6) T30Ni16Cr5:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
