B7 Stud Bolt
B7 stud bolt Coupled with pair of Nuts with is a specific type of Stud Bolt that is commonly used in high-temperature and high-pressure applications, particularly in the oil and gas industry. B7 Grade Specifically refers to ASTM A193 material used to manufacture the stud bolt. In this case, B7 is a grade of alloy steel known as AISI 4140 or ASTM A193.Sartaj offer B7 Stud bolts in both metric & imperial sizes. We produce B7 Stud bolts with full compliances to all requirements and provide full certification.
Technical Specification
ASTM A193 Grade B7 Chromium Molybendum steel, normally AISI 4140, heat treated to 28-32Rockwell Hardness, 125,000 PSI tensile strength, 105, 000 PSI yield. It will hold its strength to 1000 degrees F. This grade of studbolts are engineered to mate with ASTM A194 Grade 2H Heavy Hex Nuts.
ASTM A193 B7 bolts are built to the requirements of numerous specifications and material design properties. To be more specific, B7 alloy steel is a high temperature grade of A-193. B7 steel is also a chrome moly steel with a minimum tensile strength of 125ksi.
