Strong Match — 87.1% match
based on chemical composition and mechanical property overlap.
JIS G3506 SWRH77B (JIS G3506:2004) and IS 1875 Class 6 (IS 1875:1992) are both steel grades.
Both fall under the Carbon Steel category.
JIS G3506 SWRH77B is typically used for high-carbon hard-drawn steel wire rod (sw-c class, 0.80% c); used for hard-drawn steel wire, oil-tempered wire, prestressed concrete (pc) wire/strand, galvanized wire strands, wire rope, springs, tire bead wire, while IS 1875 Class 6 is commonly used for billets, blooms, slabs and bars for general engineering forgings.
JIS G3506 SWRH77B is defined under Japanese Industrial Standards (JIS), originating from Japan, while IS 1875 Class 6 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, JIS G3506 SWRH77B vs IS 1875 Class 6 is a 87.1% 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 87.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
