Close Alternative — 80.9% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 170H41 (BS 970 (Part 1):1991) and IS 1570 (Part 4) 36Si7 (IS 1570 (Part 4):1988) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 (Part 1) 170H41 is defined under British Standards (BS), originating from United Kingdom, while IS 1570 (Part 4) 36Si7 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 1) 170H41 vs IS 1570 (Part 4) 36Si7 is a 80.9% 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 80.9%.
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) 170H41 specifies B which is not specified for IS 1570 (Part 4) 36Si7.
IS 1570 (Part 4) 36Si7 specifies Si which is not specified for BS 970 (Part 1) 170H41.
Can BS 970 (Part 1) 170H41 Be Substituted With IS 1570 (Part 4) 36Si7?
BS 970 (Part 1) 170H41 and IS 1570 (Part 4) 36Si7 are a close alternative rather than a direct substitute. Some properties overlap well, but check the specific chemistry and mechanical rows above against your application's requirements before treating them as interchangeable.
