ASTM A320 L7S MATERIAL PROPERTIES

ASTM A320 L7S MATERIAL PROPERTIES

ASTM A320 L7S MATERIAL PROPERTIES

(OP)
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.

RE: ASTM A320 L7S MATERIAL PROPERTIES

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.

Regards,

Cory
