Dacromet stud bolt

Dacromet stud bolts are manufactured with a corrosion-resistant coating based on metallic and non-metallic compounds, typically 8 to 12 microns thick. This coating resists rust, acids, and corrosive chemical environments, thereby extending the service life of connections. Dacromet stud bolts are generally made from carbon steel with tensile strengths ranging from 70 to 110 ksi. Common diameters range from 1/4 inch to 2 inches, and threads are produced according to ASME B1.1 standards with high precision. Surface hardness after coating ranges between 200 and 280 Brinell.

Dacromet stud bolts are widely used in oil, gas, petrochemical industries, and metal structures requiring high corrosion resistance. The Dacromet coating process involves surface preparation, coating application, and heat curing, which enhance adhesion and durability. Quality control tests include coating thickness, tensile strength, hardness, and non-destructive testing. These stud bolts, with their special anti-corrosion properties, reduce maintenance costs and ensure connection stability under harsh environmental conditions.
