B7 Studs

A B7 stud, often referred to as an ASTM A193 Grade B7 stud, is a type of threaded fastener that is made from a specific alloy steel known as Grade B7. These studs are designed and manufactured to meet the ASTM A193 standard, which outlines the requirements for high-temperature and high-pressure bolting materials. Key characteristics of B7 studs include: Material: B7 studs are typically made from a chromium-molybdenum steel alloy known for its high tensile strength and excellent mechanical properties. High-Temperature Resistance: Grade B7 steel maintains its strength and integrity at elevated temperatures, making it suitable for applications in high-temperature environments. Corrosion Resistance: While not inherently corrosion-resistant like stainless steel, B7 studs are often coated or plated to enhance their resistance to corrosion. B7 studs are commonly used in industries such as petrochemical, oil and gas, and power generation, where high-strength fasteners are required for flanged connections, pressure vessels, and other critical applications. They are often used with Grade 2H heavy hex nuts, which are also specified in the ASTM A193 standard. These studs are available in various diameters and lengths to suit different bolting needs.
