Close Alternative — 80.9% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 4) 20Mn5Cr5 (IS 1570 (Part 4):1988) and EN 10084 16MnCr5 (EN 10084:2008) are both steel grades.
Both fall under the Alloy Steel category.
IS 1570 (Part 4) 20Mn5Cr5 is defined under Bureau of Indian Standards (IS), originating from India, while EN 10084 16MnCr5 is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 1570 (Part 4) 20Mn5Cr5 vs EN 10084 16MnCr5 is a 80.9% 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 80.9%.
