COR-TEN STEEL FOR STACK

[leoromboli]

Dear All,
do you think is possible to use cor-ten steel for a stack with smokes at 370°C?
Could you suggest an alternative material and relevant data sheet for this range of temperature?
Thank fro you help

Based on your information above, Corten-B steel would be preferred. You can search for further information.

Thanks for your quick reply.

Where can I find a diagram of strenth and Young module in function of temperature for Corten B?

leoromboli;
My suggestion would be to use the web site below and establish a knock-down factor for the Corten-B steel as with other stated steel grades;

For Young's Modulus you can search and find this information for carbon/low alloy steels and use the same approach for Corten-B steel.

Look up the properties in the back of the ASME B&PV Code. They have tables at the back of Sec II that give properties at various temperatures.

YOu have to be careful using corten if the oxide layer can be easily worn away... it will corrode faster. Corten is OK as long as the oxide surface remains; it is a tighter oxide layer that minimises additional rusting. If it is worn off, then the new surface forms an oxide layer that is scoured away faster than normal steel.
