IS 11169 (Part 1) 25C4 vs IS 1570 (Part 2/Sec 1) 25C4
Strong Match — 100% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 25C4 (IS 11169 (Part 1):1984) and IS 1570 (Part 2/Sec 1) 25C4 (IS 1570 (Part 2/Sec 1):1979) are both steel grades.
Both fall under the Carbon Steel category.
IS 11169 (Part 1) 25C4 is defined under Bureau of Indian Standards (IS), originating from India, while IS 1570 (Part 2/Sec 1) 25C4 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, IS 11169 (Part 1) 25C4 vs IS 1570 (Part 2/Sec 1) 25C4 is a 100% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 100%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
