ASTM A320 L7S MATERIAL PROPERTIES

[skotten]

i have a spec from a client which list 2 materials, ASTM A320 L7M and ASTM A320 L7S. i can find a spec for ASTM A320 L7M and ASTM A320 L7 but i can find absolutly nothing on ASTM A320 L7S. dose it exist or could it be that it is the same thing as ASTM A320 L7.

There is no such designation as L7S. Here are the designations in ASTM A 320:

L7, L7A, L7B, L7C, L7M, L70, L71, L72, and L73.

Perhaps the L7S is a typographic error, or maybe a printing quality problem (scanner, fax, etc.) with L7B or L73, which are similar characters.
