ASTM A331 LV GR 4140

Our client require round bar with STD A331 LV GR 4140. but our supplier is giving as per STD a29-12E1 Gr 4140 AS a331 IS WITHDRAWN. I was checking test certificate & compared with A29. I found chemical composition but could not find mechanical properties & hardness value in A29. Also, test certificate mentions metallurgical properties (Micro inclusion rating as per ASTM) & Grain size as per ASTM. I could not find reference for these in A29. Can any one help me

RE: ASTM A331 LV GR 4140

ASTM A331 was withdrawn and replaced by ASTM A108. You need to use ASTM A108 for more information.

RE: ASTM A331 LV GR 4140

Corypad,thanks. Is there any reference that a108 is the replacement std instead of a331
