ASTM A193 Grade B6X Sample MTC Certificate
Access a comprehensive, professionally formatted Material Test Certificate according to EN 10204-2004: 3.1 for ASTM A193 Grade B6X (Martensitic 410 Stainless Steel / UNS S41000). Inspect the exact documentation your QA and engineering teams will receive with every Ananka Fasteners order.
What's Inside This ASTM A193 B6X MTC Certificate
This sample mill test certificate mirrors the rigorous QA documentation package standard for martensitic, highly hardenable stainless steel fasteners shipped from Ananka Fasteners Pvt Ltd.
- Full Traceability: Certified with TC No.: S170/26-XX and corresponding ASTM specifications.
- Martensitic Chemistry: Detailed breakdowns verifying the classic 11.5% - 13.5% Chromium and 0.15% max Carbon limits of Type 410 stainless. This chemistry allows the material to be hardened by heat treatment to achieve extremely high strength levels while maintaining basic corrosion resistance.
- Specialized B6X Tempering: Verification that the material has been quenched and tempered. Grade B6X specifically dictates a lower tempering temperature (min 593°C / 1100°F) and a strictly controlled hardness range (26 HRC max) to provide excellent strength combined with compliance to NACE MR0175 for sour gas service.
- Mechanical Properties: Comprehensive reporting of Tensile Strength (Min 620 MPa), Yield Strength (Min 450 MPa), Elongation (Min 16%), and Hardness (Max 26 HRC / 262 HBW).
- Quality Compliance: 100% visual inspection carried out and verified free from defects and radioactive contamination.

Technical FAQs — ASTM A193 Grade B6X MTC Certificate
What is the difference between Grade B6 and B6X?
Both are martensitic 410 stainless steel. Grade B6 is tempered at a minimum of 649°C (1200°F) and allows a maximum hardness of 35 HRC, yielding a stronger but harder fastener. Grade B6X is designed specifically for sour gas environments (NACE compliance). It requires a lower minimum tempering temperature of 593°C (1100°F) and enforces a strict maximum hardness of 26 HRC. This controlled lower hardness drastically reduces the risk of hydrogen embrittlement and sulfide stress cracking.
Is Grade B6X corrosion resistant?
Type 410 is a martensitic stainless steel with approximately 12% chromium. It provides basic corrosion resistance against mild atmospheres, fresh water, and mild chemicals. However, it is significantly less corrosion-resistant than austenitic grades (like 304 or 316). It is chosen primarily for applications requiring high mechanical strength combined with moderate corrosion resistance, typically in petrochemical settings.
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.
