FAQs

What makes Incoloy 801 different from 800H?

Incoloy 801 is a further stabilized variant of 800H, with better resistance to grain boundary embrittlement due to carefully controlled additions of aluminum and titanium. It is ideal for long-term use in high-temperature oxidizing environments.

Where is Incoloy 801 typically used?

It’s used in reformer tubes, radiant coils, burners, convection section piping, and furnace internals. Its thermal stability and oxidation resistance make it a favorite in chemical and petrochemical industries.

Can Incoloy 801 be used in pressure vessels?

Yes, it is listed in ASME Boiler & Pressure Vessel Code and suitable for long-term operation under high heat and stress.

Is Incoloy 801 weldable?

Yes. It can be welded using standard techniques such as TIG or SMAW with ERNiCr-3 or Inconel fillers. Preheat is not typically required, but interpass temperatures should be monitored.

What are the typical lead times for GCC customers?

From Dubai: 5–8 business days
From China: 4–6 weeks
For heavy-wall or custom OD pipes: 6–8 weeks
