AISI 310 for high temperature

[JamyFilter]

Hello,

We have a pressure vessel for a project that is working at low pressure (between - 0.3 bar and 0.1 bar) but at high temperature (design temperature is 1050 °C).

We have choosen the AISI 310 but vessel manufacturer can only design at max 800°C (with ASME VIII).

1/ Do you think this stainless stell is OK at these conditions

2/ Which code do we have to choose for the design (no U-stamp required)

3/ Where can we find data about this stainless steel at this temperature.

4/ What kind of economical stainless steels are used for high temperature applications

Thanks for all your replies.

Regards.

You need to provide more information before anyone can help with all the questions. At the temperature you show there are more issues that just strength You need to determine if high temperature degradation issues, such as carburization, sulfidation, oxidation, nitridation are an issue based on the process. So lots of process information is needed.

You may be better off with a low alloy with refractory lining which gives you a lower shell temperature.

You can design using ASME Div 1.

I think MikeMet is correct with his advice. I worked with 1500 deg C internal temperature under 10 barg and used carbon steel for the shell by providing sofisticated ceramic insulation materials inside the vessel and at the nozzle internal.

I know that ASME code tables show some material allowables at around that temperature, however the atmosphere in the vessel is very important factor to deal as Mike mentioned.

You are looking for economy for the material as well. My approach to this kind application is to start with the isolation of the temperature/atmosphere at the source. The rest becomes very easy, and similar to the ordinary applications, and some other related problems disappear, such as attachment of vessel supports and their design issues.

This vessel have to be used in the process of combustion of waste. It means that we have oxidation ... I hope this info is enough to get some advices.

Salanty could you give more details/explanations about your way of working. I am not sure to understand what you mean.

In waste combustion, the shell will no doubt be exposed to more than oxidation. Under the pressure identified, ASME VIII need not apply.

Agree with the other responders, refractory lined carbon steel is better choice.
