Related Material — 65% match
based on chemical composition and mechanical property overlap.
ASTM A681 D7 (ASTM A681:2008) and IS 1570 (Part 4) XT160Cr48 (IS 1570 (Part 4):1988) are both steel grades.
ASTM A681 D7 is classified under Tool & Die Steels, while IS 1570 (Part 4) XT160Cr48 is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below.
ASTM A681 D7 is defined under ASTM International, originating from United States, while IS 1570 (Part 4) XT160Cr48 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A681 D7 vs IS 1570 (Part 4) XT160Cr48 is a 68.2% 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 65%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
