Product Description

STUD BOLTS

ASTM A193, Grade B7 STUDS are heat-treated chromium-molybdenum steel widely used for and high-temperature services like bolting material for pressure vessels, valves, flanges, and fittings for high temperature or high pressure service, or other special purpose applications.
Other grades including ferritic steels and austenitic stainless steels designated B5, B8, and so forth are also in our manufacturing range. Selection will depend upon design, service conditions, mechanical properties, and high temperature characteristics. Material according to ASTM A193 B7 is often available in Unified National Coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8 threads per inch (TPI) for diameters above one 
The STUDS are heat treated to good Hardness, higher yield and tensile strength. It holds its strength to 1000 °F. 

 It is designed to better distribute axial stresses. It undergoes special rolled thread which provides extra strength and enhances fatigue resistance quality because the metal is "rolled" up to the major diameter, not removed. This preserves and enhances the grain of the steel. Whereas full bodied cut thread studs are weaker because metal is removed to create the thread, disturbing the grain of the steel.
