Stainless steel stud bolts are manufactured from corrosion-resistant steel grades such as 304, 316, and 321. Their chemical composition includes approximately 18% chromium and 8–10% nickel. This alloy ensures structural stability at elevated temperatures up to 870°C. The tensile strength typically ranges between 515 and 860 MPa, while yield strength falls between 205 and 520 MPa. Threads are machined to metric or inch standards, with precise tolerance classes such as 6g or 2A. Most surfaces are plain and polished, although passivated or electroplated finishes may be used in specific applications.
Stainless steel stud bolts are engineered for corrosive environments such as refineries, chemical plants, and marine applications. They show excellent resistance to sulfuric acid, chloride, and salt-laden steam. These stud bolts are usually paired with stainless steel nuts like A194 Grade 8 or A2-70. In high-pressure flange systems, Grade 316 is preferred due to its molybdenum content, offering superior resistance to pitting corrosion. Surface hardness ranges from 150 to 250 Brinell, supporting ease of installation and creep resistance. Dimensions comply with ASME B18.31.2 or DIN 976 standards, ensuring compatibility across industrial systems.
