ASTM A193 Grade B8T & B8TA Sample MTC Certificate
Access a comprehensive, professionally formatted Material Test Certificate according to EN 10204-2004: 3.1 for ASTM A193 Grade B8T and B8TA (AISI 321 / UNS S32100). Inspect the exact documentation your QA and engineering teams will receive with every Ananka Fasteners order.
What's Inside This ASTM A193 B8T / B8TA MTC Certificate
This sample mill test certificate mirrors the rigorous QA documentation package standard for Titanium-stabilized austenitic stainless steel fasteners shipped from Ananka Fasteners Pvt Ltd.
- Full Traceability: Certified with TC No.: S102/26-XX and corresponding ASTM specifications.
- Titanium Stabilized Chemistry: Detailed breakdowns verifying the addition of Titanium (Ti) to the AISI 321 base chemistry. This critical element ties up carbon to prevent chromium carbide precipitation, making it exceptionally resistant to intergranular corrosion in high-temperature service (up to 870°C).
- Solution Treatment Verification: Confirms the material is carbide solution treated. For B8TA (Class 1A), it specifically verifies the treatment occurred in the finished condition to eliminate all residual stresses.
- Mechanical Properties: Comprehensive reporting of Tensile Strength (Min 515 MPa), Yield Strength (Min 205 MPa), Elongation (Min 30%), and controlled maximum Hardness (96 HRB for B8T, 90 HRB for B8TA).
- Quality Compliance: 100% visual inspection carried out and verified free from defects and radioactive contamination.

Technical FAQs — ASTM A193 Grade B8T & B8TA MTC Certificate
Why is Titanium added to the chemistry of B8T / B8TA?
Grade B8T and B8TA are made from AISI 321 stainless steel. The addition of Titanium (typically 5 times the carbon content) acts as a stabilizing agent. In high-temperature environments (425–870°C), titanium bonds with carbon to form titanium carbides, preventing the formation of chromium carbides at the grain boundaries. This prevents "sensitization" and protects the fastener against intergranular corrosion and weld decay.
What is the exact difference between Grade B8T and B8TA?
While both are Titanium-stabilized 321 stainless steel, Grade B8T (Class 1) is carbide solution treated prior to final machining and threading. Grade B8TA (Class 1A) is carbide solution treated in the finished condition (after all forming is complete). This final heat treatment removes any residual stresses caused by cold working, resulting in a softer, highly ductile fastener with a strict maximum hardness of 90 HRB (compared to 96 HRB for B8T).
Are the materials verified to be free from radioactive contamination?
Yes, the MTC document strictly states that the material has been verified as free from radioactive contamination and has undergone a 100% visual inspection to ensure it is completely free from manufacturing defects before dispatch.
