ASTM A193
Stud Bolt Description
Definition of stud bolt: a bolt with threads on both ends designed to be screwed permanently into a fixed part at one end and to receive a nut on the other
Stud bolts can be made from many different grades of material, but the most common materials are listed below. The A193 and A320 pages provide the chemical and mechanical properties of these material grades below.
CARBON STEEL
A193 B7 – This is the most common grade for which stud bolts are produced. B7 is a Chrome-moly, Alloy steel that is made to AISI 4140/4142, and it is quenched and tempered.
A193 B7M – The “M” here stands for Modified (heat treated) B7 material
A193 B16 - Chrome-moly-vanadium, Alloy steel, AISI 4140/4142 quenched and tempered
A320 L7 - AISI 4140/4142 quenched and tempered Alloy steel
A320 L43 - AISI 4340 quenched and tempered Alloy Steel
STAINLESS STEEL
A193 B6 – Heat treated 410 stainless (410HT)
A193 B8 – Produced to grade AISI 304, carbide solution treated, standardly available in class 1
A193 B8M – Produced to grade AISI 316, carbide solution treated, standardly available in class 1
A193 B8C- Grade 347 stainless material
A193 B8T – Grade 321 stainless material
A320 B8 - Produced to grade AISI 304, carbide solution treated, standardly available in class 1
A320 B8M - Produced to grade AISI 316, carbide solution treated, standardly available in class 1
A193 VS A320
A193 is the ASTM standard covering alloy 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. Material selection depends on design, service conditions, mechanical properties, and temperature characteristics. This material is often available in UNC thread pitches. If being used in traditional applications, threads are specified 8 threads per inch or 8UN for diameters above one inch.
A320 is the ASTM specification covering alloy steel and stainless bolting materials used in low-temperature services. A320 covers rolled, forged, or strain hardened bars, bolts, and stud bolts used for pressure vessels, valves, flanges, and fittings. As in A193, UNC threads are available but 8UN is standard on fasteners larger than 1" in diameter.
