These stud bolts are made from carbon steel grades that have carefully controlled levels of carbon, manganese, phosphorus, and sulfur. The carbon content gives them their strength and hardness, while heat treatment processes boost their mechanical properties. They provide excellent tensile strength, yield strength, and toughness, allowing them to handle high-stress situations. Depending on the specific grade, they can also offer moderate resistance to wear and temperature changes. Various surface finishes, such as black, zinc-plated, or hot-dip galvanized, can be applied for extra protection.
