Product Description

ASME SA193/SA193M Stud Bolts ASTM A193/A193M / Grade B7 Stud with2H Heavy Hex Nut

1.Materials A193 B7 B7M
1)ASTM A193 is alloy steel bolting material for pressure vessels, valves, flanges, and fittings for high temperature or high pressure service, or other special purpose applications.
Material according to ASTM A193 B7 is often available in national coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8 threads per inch (tpi) for diameters above one inch.

2)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.

2.Threaded Rods sizes we can offer:   1/4"-4"
