Norman Nickel Alloys stands out as a top-notch manufacturer and supplier of high-performance Alloy Steel B7 Stud Bolts right in Kuala Lumpur, Malaysia. We specialize in crafting fasteners that are built to endure the toughest industrial conditions. Our B7 stud bolts are made from quenched and tempered chromium-molybdenum alloy steel, providing outstanding tensile strength, hardness, and the ability to handle high temperatures. With rigorous quality control and adherence to ASTM A193 standards, these bolts are a go-to choice for industries like oil and gas, petrochemical, power generation, and heavy engineering, where reliability, safety, and durability are absolutely crucial.
Typically, Alloy Steel B7 Stud Bolts contain 0.37–0.49% carbon, 0.65–1.10% manganese, 0.80–1.10% chromium, and 0.15–0.25% molybdenum, along with small amounts of silicon, phosphorus, and sulfur. They boast a tensile strength of around 125 ksi (860 MPa), a yield strength of 105 ksi (720 MPa), and a hardness rating between 24–35 HRC. This perfect blend of strength, toughness, and heat resistance makes them ideal for bolting applications in high-pressure and high-temperature settings.
