What is Carbon Steel Fasteners?

Carbon Steel Fasteners are primarily composed of iron with carbon content typically ranging from 0.05% to 0.45%, depending on the grade. Small amounts of manganese, silicon, sulfur, and phosphorus may be present to enhance strength and machinability. Low-carbon steel fasteners offer good ductility and weldability, while medium-carbon grades provide higher tensile strength and hardness after heat treatment. Mechanically, carbon steel fasteners exhibit excellent tensile strength, shear resistance, and fatigue performance, making them suitable for applications requiring secure and long-lasting fastening.
