Stainless Steel 347 Sample MTC Certificate
Access a comprehensive, professionally formatted Material Test Certificate according to EN 10204-2004: 3.1 for Stainless Steel 347 (ASTM A193 Gr B8C / UNS S34700). Inspect the exact documentation your QA and engineering teams will receive with every Ananka Fasteners order.
What's Inside This SS 347 MTC Certificate
This sample mill test certificate mirrors the rigorous QA documentation package standard for stabilized, high-temperature austenitic stainless steel orders shipped from Ananka Fasteners Pvt Ltd.
- Full Traceability: Certified with TC No.: S73/26-27 and corresponding ASTM specifications.
- Stabilized Chemistry: Detailed breakdowns verifying the critical addition of Columbium/Niobium + Tantalum (Nb+Ta), which must be a minimum of 10 times the Carbon content. This stabilization prevents chromium carbide precipitation during welding or high-temperature exposure.
- Heat Treatment Verification: Verified Carbide Solution Treated (Solution Annealed) followed by a rapid Water Quench to ensure maximum corrosion resistance.
- Mechanical Properties: Comprehensive reporting of Tensile Strength (550.40 MPa), Yield Strength (245.60 MPa), Elongation (42.50%), and Hardness (82, 84, 83 HRB).
- Quality Compliance: 100% visual inspection carried out and verified free from defects and radioactive contamination.

Technical FAQs — Stainless Steel 347 MTC Certificate
Why is Columbium/Niobium carefully monitored on this MTC?
Stainless Steel 347 (UNS S34700) is uniquely stabilized with Columbium (also known as Niobium) and Tantalum. The MTC specifically verifies that the Nb+Ta content is at least 10 times the carbon content. This stabilization prevents chromium carbide precipitation at grain boundaries (sensitization) during welding or operation in the 800°F - 1500°F range, maintaining the alloy's intergranular corrosion resistance.
What heat treatment methodology is tracked on this certificate?
The MTC logs a Carbide Solution Treatment (Solution Annealing) phase followed by a rapid Water Quench. This process ensures that the micro-structure is completely homogeneous and provides maximum corrosion resistance before being put into service.
Are the materials free from radioactive contamination?
Yes, the document strictly states that the material is free from radioactive contamination and undergoes a 100% visual inspection to ensure it is free from defects.
