Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 708H20 (BS 970 (Part 1):1983) and IS 1570 (Part 4) 103Cr6 (IS 1570 (Part 4):1988) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 (Part 1) 708H20 is defined under British Standards (BS), originating from United Kingdom, while IS 1570 (Part 4) 103Cr6 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 1) 708H20 vs IS 1570 (Part 4) 103Cr6 is a 61.4% 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%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.

Key Differences
BS 970 (Part 1) 708H20 specifies Mo, P, S which are not specified for IS 1570 (Part 4) 103Cr6.
IS 1570 (Part 4) 103Cr6 specifies Si which is not specified for BS 970 (Part 1) 708H20.
Can BS 970 (Part 1) 708H20 Be Substituted With IS 1570 (Part 4) 103Cr6?
BS 970 (Part 1) 708H20 and IS 1570 (Part 4) 103Cr6 share some compositional similarity but differ enough that substitution should not be assumed. Review the differences above carefully, and consult the applicable standard or a metallurgist before using one in place of the other.
