Samuel Steels is a reliable manufacturer and supplier of Alloy Steel 2HM Stud Bolts based in Abuja, Nigeria. We provide high-performance fasteners that are perfect for tough industrial and structural applications. Our stud bolts are made in line with ASTM A193 Grade 2HM standards and are heat-treated to achieve exceptional tensile strength, hardness, and toughness. These Alloy Steel 2HM Stud Bolts are specifically designed for high-pressure and high-temperature settings, ensuring that joints remain secure even under extreme conditions. At Samuel Steels, we prioritize precision threading, dimensional accuracy, and corrosion resistance, making our bolts ideal for refineries, power plants, petrochemical facilities, and heavy engineering sectors where safety and durability are paramount.
Alloy Steel 2HM Stud Bolts are made up of carbon (0.20–0.25%), manganese (0.60–0.90%), silicon (0.15–0.35%), chromium (0.80–1.15%), molybdenum (0.15–0.25%), with phosphorus (0.035% max) and sulfur (0.040% max) in minimal amounts, while the rest is iron. They boast a minimum tensile strength of 860 MPa and a yield strength of 655 MPa. These bolts are known for their impressive hardness, fatigue resistance, and heat stability after undergoing quenching and tempering. The Cr-Mo alloying provides excellent corrosion and oxidation resistance, ensuring reliable performance in high-stress bolting and flange assembly tasks.
