Strong Match — 90% match
based on chemical composition and mechanical property overlap.
IS 1875 Class 2A (IS 1875:1992) and BS 970 (Part 1) 070M26 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Carbon Steel category.
IS 1875 Class 2A is typically used for billets, blooms, slabs and bars for general engineering forgings, while BS 970 (Part 1) 070M26 is commonly used for wrought steel for mechanical and allied engineering purposes; supplied in the normalized condition (table 2)..
IS 1875 Class 2A is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 070M26 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 1875 Class 2A vs BS 970 (Part 1) 070M26 is a 90% 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 90%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
