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.
ASTM A320: L7, L7M, L43, B8 class 1, B8 class 2, B8M class 1, B8M
class 2, B8T etc.
Our supplied sizes:1/2"-4"
Surface finish: Self black, Blacken,Zinc-coated, GI and so on
