Strong Match — 91% match
based on chemical composition and mechanical property overlap.
JIS G4051 S55C (JIS G4051:2009) and JIS G3506 SWRH62B (JIS G3506:2004) are both steel grades.
Both fall under the Carbon Steel category.
JIS G4051 S55C is typically used for springs, gears, cutting tools, high strength shafts, 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.
JIS G4051 S55C is defined under Japanese Industrial Standards (JIS), originating from Japan, while JIS G3506 SWRH62B is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, JIS G4051 S55C vs JIS G3506 SWRH62B 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.
