ASTM A193 B8 Class 2 stud bolts are strain hardened, providing higher tensile and yield strength compared to ASTM A193 B8 Class 1 stud bolts. These properties make them suitable for valve, flange, and piping assembly where reliable tightening is required. Prior to dispatch, the stud bolts undergo inspection and testing to verify mechanical properties and dimensional accuracy. The material is marked in accordance with ASTM A193 requirements, including the B8 Class 2 identification.

ASTM A193 B8 Class 2 stud bolts offer corrosion resistance associated with austenitic stainless steel, along with improved strength from the strain hardening process. Carbide solution treatment supports consistent mechanical performance during service. Supply is available in standard as well as custom sizes, with configurations including threaded, tap end, double end, and flange stud bolts. Orders are processed based on project specifications and application requirements.

Manufacturing is carried out using controlled production methods to maintain thread accuracy and surface finish. Stud bolts are supplied with suitable finishing and minimal burr formation for proper fitment during installation. Delivery can be arranged for both project and maintenance requirements, with documentation provided as specified.
