Close Alternative — 74% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 7) 15Mo6H (IS 1570 (Part 7):1992) and SAE J404 4023 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
IS 1570 (Part 7) 15Mo6H is typically used for boilers, pressure vessels, steam turbines, steam and water piping and other power plant equipment working at elevated temperature, while SAE J404 4023 is commonly used for chemistry-only alloy steel grade; see the composition notes for product scope.
IS 1570 (Part 7) 15Mo6H is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 4023 is defined under SAE International, originating from United States.
As per chemical composition, IS 1570 (Part 7) 15Mo6H vs SAE J404 4023 is a 74% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 74%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
