High-Quality Stainless Steel B8 B8m Stud Bolts


Originally approved in 1936, this specification is heavily utilized in petroleum and chemical construction applications. A193/A193M(A194/A194M) covers both inch and metric series products. The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature or high pressure service.

This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material 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.

Below is a basic summary of a few of the common grades. ASTM A193 covers a number of other standard specifications not covered in this description including B5, B6, and B16.
