What Are ASTM A320 Grade L7 Stud Bolts?
For the production of bolts, studs, stud bolts, and other fasteners for bolting pressure vessels, valves, flanges, and fittings for various process industries across major industrial sectors in low-temperature applications, ASTM A320 Grade L7 Stud Bolts is a material specification for chromium-molybdenum steel. Chemically ASTM A320 Grade L7 equivalent is ASTM B638 grade 660 stainless steel alloy.
ASTM A320 Grade L7 Specification
For use in high-temperature bolting applications, ASTM A320 Grade L7 material is also used for bolts, studs, nuts, and other fasteners. 
ASTM A320 L7 material Properties namely A, B, C, and D are assigned a different set of tensile stress and rupture properties. 
Boilers, ...
... pressure vessels, pipeline flanges, and valves designed for high-temperature duty are bolted together with grade 660 fasteners. 
The stainless steel alloy ASTM B638 grade 660, also known as alloy A286 and UNS S66286, and heat-treated to satisfy the qualities specified in ASTM A453 specification, is chemically equivalent to the ASTM A320 Grade L7 material.
Types Of ASTM A320 Grade L7 Stud Bolts
ASTM A320 Grade L7 Bolts: ASTM A320 Grade L7 Bolts is a material specification for high-temperature bolts, studs, nuts, and other fasteners. ASTM A320 Grade L7 is divided into four different property classes: A, B, C, and D, each having its own set of tensile and stress rupture qualities.
Astm A320 Grade L7 Stud Bolts:Astm A320 Grade L7 Stud Bolts provide the ability to obtain much more accurate torque values because the studs don't twist during tightening as do bolts. Because the studs remain stationary during nut tightening, the studs stretch in one axis alone, providing much more even and accurate clamping forces.
Types Of ASTM A193 Grade B7 Bolts
ASTM A193 Grade B7 Bolts: Due to the heat-treated chromium-molybdenum steel, ASTM A193 Grade B7 Bolts are suitable for applications up to 450°C. Bolts with external threading and a hex head known as B7 hex bolts are made to be driven by a wrench. ASTM A193 Grade B7 comes with a hex cap and can be threaded fully or partially.
Astm A193 Grade B5: For low alloy chromium-ferritic steel fasteners used in high tensile, high temperature, and special-purpose applications such as pressure piping and pressure vessel fastening, ASTM A193 Grade B5 is a standard material specification.
