Close Alternative — 84.8% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 4) 103Cr4 (IS 1570 (Part 4):1988) and GOST 801 ShKh15 (GOST 801-1978) are both steel grades.
Both fall under the Alloy Steel category.
IS 1570 (Part 4) 103Cr4 is defined under Bureau of Indian Standards (IS) (India).
As per chemical composition, IS 1570 (Part 4) 103Cr4 vs GOST 801 ShKh15 is a 84.8% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 84.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
