Related Material — 65% match
based on chemical composition and mechanical property overlap.
GOST 1435 U10 (GOST 1435-1999) and IS 1570 (Part 4) 36Si7 (IS 1570 (Part 4):1988) are both steel grades.
GOST 1435 U10 is classified under Tool & Die Steels, while IS 1570 (Part 4) 36Si7 is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below.
IS 1570 (Part 4) 36Si7 is defined under Bureau of Indian Standards (IS) (India).
As per chemical composition, GOST 1435 U10 vs IS 1570 (Part 4) 36Si7 is a 78.8% 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 65%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
