Strong Match — 91.8% match
based on chemical composition and mechanical property overlap.
IS 1875 Class 6 (IS 1875:1992) and JIS G3506 SWRH62B (JIS G3506:2004) are both steel grades.
Both fall under the Carbon Steel category.
IS 1875 Class 6 is typically used for billets, blooms, slabs and bars for general engineering forgings, while JIS G3506 SWRH62B is commonly used for high-carbon hard-drawn steel wire rod (sw-b class, 0.60-0.85% c); used for hard-drawn steel wire, oil-tempered wire, prestressed concrete (pc) wire/strand, galvanized wire strands, wire rope, springs, tire bead wire.
IS 1875 Class 6 is defined under Bureau of Indian Standards (IS), originating from India, while JIS G3506 SWRH62B is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, IS 1875 Class 6 vs JIS G3506 SWRH62B is a 91.8% 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 91.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
