AISI4140 wire is a high-quality alloy structural steel wire. AISI4140 wire has good mechanical properties. It has excellent mechanical properties, high tensile strength, and good toughness, and can withstand large loads and impacts. Its excellent hardenability allows a deeper hardened layer to be obtained during quenching, thereby greatly improving the overall strength and hardness. Good processing performance makes it relatively easy to carry out both cold and hot processing, and can be made into parts of various shapes through cold heading, cutting, welding and other processes. Moreover, it exhibits good fatigue resistance when subjected to alternating loads for a long time, ensuring the service life of the parts. AISI4140 wire is a reliable choice for many industries that require high-strength and high-performance materials.
