Close Alternative — 78.8% match
based on chemical composition and mechanical property overlap.
IS 4367 37Mn5Si5 (IS 4367:1991) and BS 970 (Part 1) 170H36 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Alloy Steel category.
IS 4367 37Mn5Si5 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 170H36 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 4367 37Mn5Si5 vs BS 970 (Part 1) 170H36 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 close alternative overall at 78.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
