Strong Match — 86.3% match
based on chemical composition and mechanical property overlap.
JIS G3506 SWRH62B (JIS G3506:2004) and BS 970 (Part 3) 070M55 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Carbon Steel category.
JIS G3506 SWRH62B is typically 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, while BS 970 (Part 3) 070M55 is commonly used for used for springs, blades, wear plates, hand tools, shafts, and cutting components..
JIS G3506 SWRH62B is defined under Japanese Industrial Standards (JIS), originating from Japan, while BS 970 (Part 3) 070M55 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, JIS G3506 SWRH62B vs BS 970 (Part 3) 070M55 is a 86.3% 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 86.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
