SS304 Sample MTC Certificate
Access a comprehensive, professionally formatted EN 10204 3.1 sample Material Test Certificate for Stainless Steel 304 (A2-70 / UNS S30400 / EN 1.4301). Inspect the exact documentation your engineering and QA teams will receive with every Ananka Fasteners order — complete with heat-traceable "18/8" chemistry and A2-70 cold-worked mechanical properties.
What's Inside This SS304 (A2-70) MTC Certificate
This sample A2-70 mill test certificate mirrors the rigorous QA documentation package shipped with every commercial-grade austenitic stainless steel order. It demonstrates how Ananka Fasteners reports critical metallurgical and mechanical data ensuring audit-readiness for food processing, architectural, and structural environments.
- Full Traceability: Heat and lot numbers linking each threaded stud, hex bolt, or nut directly back to its original melt.
- Chemical Composition: Verification of the classic "18/8" elements, including Chromium (18-20%) and Nickel (8-11%) for optimal atmospheric corrosion resistance.
- A2-70 Property Class Data: Explicit reporting of cold-worked strength levels meeting or exceeding the rigorous ISO 3506-1 requirements.
- Mechanical Properties: Verified elevated tensile strength (min 700 MPa) and yield strength (min 450 MPa) to guarantee structural load-bearing integrity.

Our SS304 MTC certificates map strictly to the most demanding international specifications. The mechanical properties explicitly verify the popular "Class 70" cold-worked condition.
| Standard | Application Focus |
|---|---|
| ISO 3506-1 (A2-70) | The defining standard for corrosion-resistant stainless steel fasteners. "A2" specifies the 18/8 austenitic grade (SS304), and "70" guarantees high-tensile cold-drawn strength (700 MPa). |
| ASTM A193 Grade B8 | Often referenced for bolting materials intended for pressure vessels, valves, and flanges for high-temperature service. |

Technical FAQs — SS304 (A2-70) MTC Certificate
What exactly does "A2-70" mean on my SS304 MTC?
"A2" designates the austenitic group alloyed with 18% Cr and 8% Ni (SS304). "70" indicates cold-worked tensile strength of 700 MPa, providing higher load capacity than standard A2-50.
Difference between SS304 (A2-70) and SS316 (A4-80)?
SS304 (A2) lacks Molybdenum, making it economical for general use. SS316 (A4) contains 2-3% Moly for protection against chloride pitting in marine environments.
