Strong Match — 91% match
based on chemical composition and mechanical property overlap.
JIS G3506 SWRH62B (JIS G3506:2004) and JIS G4051 S55C (JIS G4051:2009) 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 JIS G4051 S55C is commonly used for springs, gears, cutting tools, high strength shafts.
JIS G3506 SWRH62B is defined under Japanese Industrial Standards (JIS), originating from Japan, while JIS G4051 S55C is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, JIS G3506 SWRH62B vs JIS G4051 S55C is a 91% 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%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
