These bolts are celebrated for their impressive strength and consistent performance in critical applications, and they’re crafted with a keen eye for international standards like ASTM A193. By blending cutting-edge manufacturing techniques with strict quality control, Filiz Steel ensures that their fastening solutions are precision-engineered to meet the highest expectations. They cater to various industries, including oil & gas, petrochemicals, power generation, and heavy engineering, making them a trusted partner for anyone in need of durable, high-performance alloy steel fasteners.
Alloy Steel 2HM Stud Bolts are manufactured from chromium-molybdenum steel, providing high strength and resistance to corrosion. The standard composition is 0.28-0.36% Carbon, 0.6-1.0% Manganese, 0.75-1.2% Chromium, 0.15-0.25% Molybdenum, and trace elements for increased durability. Mechanically, 2HM Stud Bolts possess a minimum tensile strength of 100 ksi (690 MPa), yield strength of 80 ksi (550 MPa), and elongation of 18% for toughness. Their hardness is 197-237 HBW, which provides outstanding performance at high temperature and pressure in harsh industrial applications.

Alloy Steel 2HM Stud Bolts are generally made from quenched and tempered chromium-molybdenum alloy steels, which provide outstanding mechanical strength, hardness, and remarkable resistance to high-temperature and high-pressure conditions. They conform to the ASTM A193 Grade B7 or B7M specifications and are typically paired with 2HM heavy hex nuts according to ASTM A194. These stud bolts boast tensile strengths that exceed 860 MPa and yield strengths above 720 MPa, along with enhanced toughness and resistance to stress corrosion cracking, particularly in environments with hydrogen sulfide (H₂S) and sour service conditions.
Alloy Steel 2HM Stud Bolts are extensively applied in high-pressure and high-temperature applications because of their superior strength, toughness, and corrosion resistance. These stud bolts are typically utilized in oil & gas industries, petrochemical facilities, power generation, and heavy equipment where fastening is essential. They are suitable for flange joints, pressure vessels, heat exchangers, and structural assemblies in aggressive environments. Their enhanced mechanical properties recommend them for use in offshore drilling rigs, refineries, and marine environments. Alloy Steel 2HM Stud Bolts, with their ability to resist harsh conditions, provide reliable and long-lasting connections in key industrial applications.
