Technical FAQs — SS321 MTC Certificate

What is Titanium stabilization (Ti)?

Titanium is added to 321 stainless steel to stabilize the carbide structure. By adding Titanium at a minimum of 5x the carbon content, we prevent the formation of chromium carbides, which would otherwise lead to intergranular corrosion at high temperatures.

Why is this grade used in high-temp service?

SS321 is ideal for service in the sensitization range of 427°C to 816°C. The Titanium addition allows it to maintain its structural integrity and corrosion resistance where standard 304 or 316 might suffer.

Is this a full 3.1 MTC?

Yes, all Ananka Fasteners test reports are issued in accordance with EN 10204-2004: 3.1, providing traceable results per specific production heat and lot.
