GOST 1050 45 vs IS 1570 (Part 4) 15Cr6Ni6

Related Material — 65% match based on chemical composition and mechanical property overlap.

GOST 1050 45 (GOST 1050-2013) and IS 1570 (Part 4) 15Cr6Ni6 (IS 1570 (Part 4):1988) are both steel grades. GOST 1050 45 is classified under Carbon Steel, while IS 1570 (Part 4) 15Cr6Ni6 is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below. IS 1570 (Part 4) 15Cr6Ni6 is defined under Bureau of Indian Standards (IS) (India).

As per chemical composition, GOST 1050 45 vs IS 1570 (Part 4) 15Cr6Ni6 is a 65.2% 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%.
