ASTM A320 Bolts
ASTM A320 Bolts is intended for low-temperature service down to -150° F and has a minimum Charpy impact value of 20-ft-lbf at this temperature. ASTM A320 Hex Bolts has to get high temperature or high pressure & corrosion resistant steels durability and service. ASTM A320 Stud Bolts has different sizes and patterns our premium quality ASTM A320 Grade L7 AS Bolts is greatly demanded in the market for their speculative features & specifications.
The specification for ASTM A320 Grade L7m Material covers both alloy steel as well as stainless steel bolting materials to be used for low temperature applications. The ASTM A320 L7 Stud Bolts can also be used in applications where the temperature of the environment reaches up to - 150ºF. And the ASTM A320 Grade L7m Bolts and ASTM A320 Bolts has a minimum Charpy impact value of 15 ft-lb at this temperature.
Standard ASTM A320 Grade L7 Stud Bolts covers up those fittings in which the alloy has been rolled, forged, or strain hardened bars, bolts, screws, studs, and stud bolts. These ASTM A320 Gr L7 Stud Bolt have been used for applications involving pressure vessels, valves, flanges, and fittings.Similar to the ASTM A193 standard, the 8UN thread series is specified on the A320 Gr L7 Material fastener is known to measure larger than 1” in diameter.The alloy steel for standard ASTM A320 Grade L7 Nuts has to undergo AISI 4140/4142 Quenching and tempering.
