Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10084 28CrS4 (EN 10084:2008) and IS 1570 (Part 7) 10Cr36Mo10H (IS 1570 (Part 7):1992) are both steel grades.
Both fall under the Alloy Steel category.
EN 10084 28CrS4 is typically used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1), while IS 1570 (Part 7) 10Cr36Mo10H is commonly used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature.
EN 10084 28CrS4 is defined under European Standard (EN), originating from Europe, while IS 1570 (Part 7) 10Cr36Mo10H is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10084 28CrS4 vs IS 1570 (Part 7) 10Cr36Mo10H is a 60.5% 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.
