Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
AISI 8615 and IS 1570 (Part 4) 105Cr5 (IS 1570 (Part 4):1988) are both steel grades.
Both fall under the Alloy Steel category.
AISI 8615 is defined under AISI, originating from United States, while IS 1570 (Part 4) 105Cr5 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, AISI 8615 vs IS 1570 (Part 4) 105Cr5 is a 58.6% 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.
