What's Inside This ASTM A193 B8M Class 1 MTC Certificate
This sample mill test certificate mirrors the rigorous QA documentation package standard for highly durable marine-grade austenitic stainless steel fasteners shipped from Ananka Fasteners Pvt Ltd.
- Full Traceability: Certified with TC No.: S91/26-XX and corresponding ASTM specifications.
- Molybdenum Enriched Chemistry: Detailed breakdowns verifying the addition of 2.00% - 3.00% Molybdenum. This critical element vastly improves resistance to pitting and crevice corrosion in chloride environments (like seawater) compared to standard B8 (304) grades.
- Class 1 Carbide Solution Treated: Verification that the material is solution annealed and un-strain-hardened, ensuring maximum corrosion resistance and excellent ductility under extreme conditions.
- Mechanical Properties: Comprehensive reporting of Tensile Strength (Min 515 MPa), Yield Strength (Min 205 MPa), Elongation (Min 30%), and a strictly controlled maximum Hardness of 96 HRB.
- Quality Compliance: 100% visual inspection carried out and verified free from defects and radioactive contamination.

Technical FAQs — ASTM A193 Grade B8M Class 1 MTC Certificate
What is the difference between Grade B8 and Grade B8M?
Grade B8 is manufactured from AISI 304 stainless steel, while Grade B8M is manufactured from AISI 316. The key difference shown on the MTC is the addition of 2.00% to 3.00% Molybdenum in B8M. This significantly enhances the fastener's resistance to pitting and crevice corrosion, making it the preferred choice for marine, offshore, and harsh chemical environments.
What does "Class 1" mean for B8M fasteners?
Class 1 denotes that the fasteners have been carbide solution treated (annealed) but not intentionally strain-hardened. This provides excellent ductility and corrosion resistance, keeping the maximum hardness to 96 HRB. By contrast, Class 2 fasteners are strain-hardened to achieve higher tensile and yield strength, though they sacrifice some ductility in the process.
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.
