What's Inside This Grade 2 (316/316L) MTC Certificate
This sample mill test certificate mirrors the rigorous QA documentation package standard for highly pitting-resistant, molybdenum-bearing austenitic stainless steel nuts shipped from our facilities.
- Full Traceability: Certified with TC No.: N88/24-XX and corresponding ASTM F594 specifications.
- Marine-Grade Chemistry: Detailed breakdowns verifying the essential Molybdenum (2.00–3.00%), Chromium (~16.50%), and Nickel (~10.50%) content, providing exceptional resistance to chlorides and pitting corrosion.
- Dual Certification Compatibility: Explicit verification of the low carbon content (0.03% max for the 'L' designation), ensuring compliance with both standard 316 strength requirements and 316L weldability standards.
- Mechanical Properties: Comprehensive reporting of Tensile Strength (585.50 MPa), Yield Strength (260.20 MPa), Elongation (48.50%), and Hardness (82, 84, 83 HRB) per ASTM requirements for machined/annealed condition.
- Quality Compliance: 100% visual inspection carried out and verified free from defects and radioactive contamination.

Technical FAQs — ASTM F594 Grade 2 (316/316L) MTC
Why is Molybdenum tracked so closely on this certificate?
The addition of 2.00–3.00% Molybdenum is what separates 316 from standard 304 stainless steel. This MTC validates the exact Molybdenum percentage, ensuring the nuts possess enhanced resistance to pitting and crevice corrosion, especially in chloride-rich environments like marine applications and de-icing salt exposure.
What does "Dual Certification" (316/316L) mean on this MTC?
The chemistry section shows a maximum Carbon content below 0.030% (the "L" requirement), while the mechanical properties meet the higher tensile and yield strength requirements of standard 316. This means the fasteners are "Dual Certified," offering both the structural integrity of 316 and the superior weldability/carbide precipitation resistance of 316L.
Are these nuts compatible with standard ASTM F593 bolts?
Yes. ASTM F594 Grade 2 nuts are the direct specified counterpart for ASTM F593 Alloy Group 2 stainless steel bolts. They are engineered to provide matching galling resistance, strength, and corrosion profiles when mated together.
