What's Inside This SS310 MTC Certificate
This sample SS310 mill test certificate mirrors the rigorous QA documentation package shipped with every heat-resistant austenitic stainless steel order. It demonstrates how Ananka Fasteners reports critical metallurgical and mechanical data ensuring audit-readiness for furnaces, heat exchangers, and thermal processing environments.
- Full Traceability: Heat and lot numbers linking each threaded stud, hex bolt, or nut directly back to its original melt.
- Chemical Composition: Verification of the high-alloy "25/20" elements, including Chromium (24-26%) and Nickel (19-22%) for supreme resistance to oxidation and sulfidation.
- Heat Treatment Records: Explicit reporting of the Carbide Solution Treatment (annealed at 1050°C and water quenched) ensuring optimal corrosion resistance and ductility.
- Mechanical Properties: Verified elevated tensile strength (min 515 MPa) and highly ductile elongation (min 40%) to accommodate thermal expansion stresses.

Technical FAQs — SS310 MTC Certificate
Why are the Chromium and Nickel contents so high on an SS310 MTC?
Stainless Steel 310 is highly alloyed with 24-26% Chromium and 19-22% Nickel. This "25/20" chemistry is explicitly designed to provide extreme resistance to oxidation, sulfidation, and scaling under continuous high-temperature service (up to 1100°C or 2012°F). Your MTC verifies this exact chemistry, ensuring standard 304 or 316 steels are not mistakenly substituted in critical heat zones.
What is "Carbide Solution Treatment" listed in the remarks?
As noted on the MTC, the fasteners are "solution annealed at 1050°C and water quenched." This critical heat treatment process dissolves any precipitated chromium carbides back into the solid matrix and rapidly cools the metal to lock them in place. This maximizes the alloy's ductility (elongation > 40%) and ensures optimal corrosion resistance before it is installed in the field.
