Strong Match — 85.1% match
based on chemical composition and mechanical property overlap.
BS 970 EN47 (BS 970:1955) and IS 3195 50Cr4V2 (IS 3195:1992) are both steel grades.
Both fall under the Spring Steel category.
BS 970 EN47 is typically used for coil springs, leaf springs, torsion bars, valve springs, suspension springs, industrial springs requiring high fatigue life., while IS 3195 50Cr4V2 is commonly used for volute and helical springs for railway rolling stock; flats and rounds, springs worked hot and heat-treated (clause 1.1, foreword).
BS 970 EN47 is defined under British Standards (BS), originating from United Kingdom, while IS 3195 50Cr4V2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 EN47 vs IS 3195 50Cr4V2 is a 85.1% 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 85.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
