What's Inside This Grade 55 MTC Certificate
This sample mill test certificate mirrors the rigorous QA documentation package standard for structural anchor bolts used in heavy construction, bridge applications, and sign structures shipped from our facilities.
- Full Traceability: Certified with TC No.: A55/26-XX and corresponding ASTM F1554 specifications.
- Weldable Chemistry (S1 Supplement): Detailed breakdowns verifying the Carbon Equivalent (CE) required by Supplementary Requirement S1, guaranteeing weldability for applications where bolts are tacked or welded to rebar cages.
- Verified Production Method: Explicit documentation of the material condition (typically as-rolled), ensuring the steel meets the demanding 55 ksi minimum yield strength necessary for foundation anchoring.
- Mechanical Properties: Comprehensive reporting of Tensile Strength (585.00 MPa / ~85 ksi), Yield Strength (410.50 MPa / ~60 ksi), Elongation (25.50%), and Hardness per strict ASTM F1554 Grade 55 limits.
- Quality Compliance: 100% visual inspection carried out and verified free from defects and radioactive contamination.

Technical FAQs — ASTM F1554 Grade 55 MTC
What does the "55" signify in ASTM F1554 Grade 55?
The "55" represents the minimum yield strength requirement of the anchor bolt in thousands of pounds per square inch (ksi). As verified on the MTC, these bolts are guaranteed to withstand at least 55,000 psi (380 MPa) of yield stress, providing a significant structural upgrade over standard Grade 36 bolts.
What is the "S1" Supplementary Requirement on this MTC?
Supplementary Requirement S1 guarantees weldability. To meet this, the chemistry section of the MTC must calculate and report a Carbon Equivalent (CE) of less than or equal to 0.45%. By meeting S1, engineers are assured these anchor bolts can be safely welded to rebar grids or embedment plates on the job site without risking brittle failure in the heat-affected zone.
Can these anchor bolts be hot-dip galvanized?
Yes. Grade 55 bolts are routinely hot-dip galvanized for corrosion protection. Unlike Grade 105 bolts which require severe caution regarding hydrogen embrittlement due to high hardness, Grade 55's moderate strength and chemistry make it an excellent, safe candidate for the galvanizing process.
