Related Material — 69% match
based on chemical composition and mechanical property overlap.
ASTM A681 O1 (ASTM A681:2008) and IS 1570 (Part 6) T140W15Cr2 (IS 1570 (Part 6):1996) are both steel grades.
Both fall under the Tool & Die Steels category.
ASTM A681 O1 is defined under ASTM International, originating from United States, while IS 1570 (Part 6) T140W15Cr2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A681 O1 vs IS 1570 (Part 6) T140W15Cr2 is a 69% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
