uniaxial strain limit - Table 5.7 ASME.BPVC.VIII.2 Chapter 5 1

[tigny]

hi,

regarding 5.3.3 Protection against local failure, Elastic-plastic analysis - Local Strain Limit,
there are reference parameters ε_Lu, m₂ and α_sl to be selected in Table 5.7 depending on materials.

Table 5.7 lists Ferritic steel; Stainless steel and Nickel based Alloys; Duplex stainless steel; Precipitation hardenable nickel base alloys and other non ferrous materials.

[ul]
[li]What if the component is made of carbon steel?[/li]
[li]What values of ε_Lu, m₂ (formulaes) and α_sl should be used for carbon steel?[/li]
[/ul]

best regards

Carbon steel is a ferritic steel.

Dear TGS4

Carbon steel is a ferritic steel.

Thank you for your answer, I'm sorry I didn't react before.

I was having a confusion between Carbon steels (therefore Ferritic Steels) such as in Division 1 UCS,
and Ferritic Steels [highlight #FCE94F]With Properties Enhanced by Heat Treatment[/highlight] such as in Division 1 UHT. The other few references in Division 2 allow to make the same disctinction.

Now this makes sense, thank you again.
