Black skin bolts are mainly used for high-temperature bolts in steam turbines, gas turbines, and other applications that require high temperature resistance and strength. Black skin bolts are also used in other industrial fields that require high temperature resistance and strength, such as petrochemicals, power, metallurgy, etc. In these fields, black skin bolts are used to connect and fix key components of various high-temperature equipment, ensuring stable operation and safety of the equipment.
Black skinned molybdenum bolts are usually subjected to special surface treatment to improve their corrosion resistance and aesthetics, while ordinary molybdenum bolts do not undergo this treatment.
The surface treatment process of black skinned molybdenum bolts includes shot blasting, shot blasting, etc. These treatments can form a protective film on the surface of the bolt to prevent corrosion and oxidation. This treatment not only improves the corrosion resistance of the bolts, but also increases their service life and aesthetics. In contrast, ordinary molybdenum bolts have not undergone these special treatments, and their anti-corrosion performance and aesthetics are relatively poor.
The surface treatment of black skinned molybdenum bolts mainly includes three processes: blackening, oxidation blackening, and phosphating blackening.
