Neelkamal Alloys LLP is a leading manufacturer and reliable supplier of ASTM A193 Grade B7 Studs and ASTM A194 Grade 2H Nuts, designed for demanding industrial applications. These components are widely used in industries like petrochemicals, power generation, oil refining, and pressure vessels because they are essential for their ability to withstand high heat and strong forces.

We manufacture the ASTM A193 B7 Studs from heat-treated chromium-molybdenum alloy steel to enhance its durability and strength. Bolting flanges, valves, and fittings is a common application for these fasteners, which are well-suited for high-pressure, high-temperature service. With a typical tensile strength of 125 ksi (860 MPa) and yield strength around 105 ksi (724 MPa), they conform to stringent ASTM specifications. They are available in both full-thread and double-end thread forms, with surface finishes like plain, black oxide, or hot-dip galvanized based on application needs.

Heat-treated carbon steel, the material of ASTM A194 2H Nuts, complements the studs by providing reliable hardness and strength for pressure service. These nuts are engineered to work seamlessly with B7 studs and provide a minimum proof load of 175 ksi (1207 MPa), with Rockwell hardness values in the HRC 24–35 range. Sizes typically range from 1/4″ to 4″ in diameter, and all nuts are manufactured in accordance with ASME B18.2.2 standards.

Neelkamal Alloys LLP ensures full traceability and testing for every batch of fasteners supplied. All products are certified with EN 10204 3.1 and endure a series of rigorous inspections, such as mechanical property verification, hardness testing, and dimensional checks. On request, we also conduct nondestructive testing, such as ultrasonic or magnetic particle inspection, to meet project-specific standards.

With a strong supply chain network, Neelkamal Alloys LLP caters to both domestic and international markets, including the USA, Gulf countries, Europe, and Southeast Asia. We maintain a ready stock of standard measurements and also provide custom-length options to accommodate the needs of a variety of industries.
