ASM equivalent for SA 335

ASM equivalent for SA 335

ASM equivalent for SA 335

(OP)
Does anybody know an equivalent for SA 335 in ASM Standards?
Appreciate any replies!

There no ASM metal standards, did you mean ASME Material Specification?

RE: ASM equivalent for SA 335

Sorry, for confusion. I'm looking for equivalent for the steel SA 335 out of the AMS metal group.

I know that SA 335 matches P91(X10CrMoVNb9-1) in terms of properties, but I couldn't find an equivalent among AMS (Aerospace Materials Specifications) group.
Thanks!

RE: ASM equivalent for SA 335

juken;
What is your intended application? SA 335 is seamless pipe in specific alloy grades. Also, in addition to chemical and mechanical property requirements in SA 335 you have additional mechanical testing and nondestructive testing optional requirements because this specification is for pipe.

metengr,

Thank you for your replies.
I'll try to explain exactly what I want to achive.

I'd like to perform elasto-plastic analysis of steam boilers using FEM.

I know that the material the steam boiler is made of is steel X10CrMoVNb9-1.

I've been trying to find stress-strain relation for this material in order to model material behavior in the elasto-plastic range for different temperatures (20,100,200,..650'C)

As an example for 20 celsius degrees we have

strain            stress[MPa]
0            0
0,001995    435
0,004210    468
0,005646    505,5
0,008014    544,5
0,011918    586,5
0,018355    633
0,028969    682,5
0,046467    735
0,075316    792
0,122881    853,5

Unfortunately I can't get these data anywhere.
 
That's why I'm trying to find out which AMS material could have the same properties like steel X10CrMoVNb9-1 (P91), so I could check if I have this material in our database and get data.

I'll appreciate any help or suggestion where else I could find these data.

Thx,
juken

juken;
Grade 91 steel is fairly unique because it is a creep strength enhanced ferritic (CSEF) steel, and I would doubt there is an equivalent grade of steel to use for obtaining the necessary stress/strain tensile properties.

I would try to Google Grade 91 steel. Look for information from Oak Ridge National Lab because this is the origin of Grade 91 steel. You may have to purchase technical articles that contain stress strain behavior data.





 Have you reviewed any of the EN Standards regarding boiler construction?  

RE: ASM equivalent for SA 335

metengr,

Thank you for your suggestions. I probably will contact Oak Ridge National Lab.

I am also going to reviewe the EN Standards and see what I can find there.

Great thanks,

juken
