Allowable Stress Table For SA213-T23

01/14/2016 6:02 AM

Dear All
Does anyone knows where can i find the allowable stress values for material SA213-T23 in order to calculate the minimum wall thickness. Because i couldn't find it in the Table 1A of ASME Sec II Part D.
Regards,

Yes. The material supplier knows, and is available by telephone.

Does this help?

Mechanical properties for ASTM A213 T23 Low Alloy Steel

Tensile strength(min)510Mpa
Yield strength(min)400Mpa
Elongation20%
Hardness, HB220max

Permitted tolerance for OD

For all other ASME standar materials i worked with the entry is usually there in the table 1A ASME Sec II Part D for the allowable stress. Why is this material not inputed there i do not know... if so how can you calculate the minimum wall thickness without knowing the allowable stress at the operating temperature...?

It is not possible to do so without that piece of data, irrespective of who tries.
