Strong Match — 88.2% match
based on chemical composition and mechanical property overlap.
JIS G3506 SWRH77B (JIS G3506:2004) and SAE J403 1080 (SAE J403:2009) 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 SAE J403 1080 is commonly used for chemistry-only grade; product scope as listed in the composition notes.
JIS G3506 SWRH77B is defined under Japanese Industrial Standards (JIS), originating from Japan, while SAE J403 1080 is defined under SAE International, originating from United States.
As per chemical composition, JIS G3506 SWRH77B vs SAE J403 1080 is a 88.2% 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 88.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.

Key Differences
JIS G3506 SWRH77B specifies Si which is not specified for SAE J403 1080.
Can JIS G3506 SWRH77B Be Substituted With SAE J403 1080?
JIS G3506 SWRH77B and SAE J403 1080 overlap closely enough on chemistry and mechanical properties that SAE J403 1080 is often considered as a substitute for JIS G3506 SWRH77B in many applications. Always confirm the specific property range your application needs before substituting, and check with your supplier's mill certificate.
