ASTM A193 Grade B7M bolts and studs are identical in chemistry to Grade B7 (quenched and tempered medium carbon alloy steel), but have lower strength requirements and require 100% hardness testing of all fasteners manufactured in the lot. Grade B7M bolts resist chloride, sulfide, and hydrogen stress corrosion cracking (SCC) and are frequently used in sour gas service.
Our main grades for threaded ros:
ASTM A193: B7, B7M, B16, B8 class 1, B8 class 2, B8M class 1, B8M class 2, B8T etc.
