Strong Match — 91.5% match
based on chemical composition and mechanical property overlap.
ASTM A681 H11 (ASTM A681:2008) and IS 3748 XT35Cr5Mo1V3 (IS 3748:1990) are both steel grades.
Both fall under the Tool & Die Steels category.
ASTM A681 H11 is typically used for die casting dies, extrusion tooling, forging dies, while IS 3748 XT35Cr5Mo1V3 is commonly used for hot work tools and dies, such as die-casting dies and hot headers.
ASTM A681 H11 is defined under ASTM International, originating from United States, while IS 3748 XT35Cr5Mo1V3 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A681 H11 vs IS 3748 XT35Cr5Mo1V3 is a 87.2% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 91.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
