SA number for L415NB and L240MB

[CCMech]

Hi all,

Does anybody know the SA number for L415NB and L240MB?

Thanks,

The above grades are from EN standards

EN 10208-2 L240NB, L290NB, L360NB, L360QB, L240MB

L290MB, L360MB, L415MB, L415NB

Here are the search results for EN 10208-2

Looks like there is no direct ASME SA match to the above grades. There are boiler and pressure vessel steel grades in EN standards.

Thanks metengr.

Is it equivalent to API 5L?

 

[metengr]

I would say, yes.

Thanks metengr.

One more question, is it close to A106 also?

 

[metengr]

CCMech;
I don't have the EN specification for a direct comparison. Off the top of my head and knowing the A 106 specification, I would say no.

Here is what I found:

L415NB = API 5L-X60
L240MB = API 5L-B

Agree with metengr. A106 is different.
