Known for our precision and dependability, we cater to a diverse array of industries both locally and internationally. Our AISI 4340 bars and rods are celebrated for their outstanding strength, toughness, and fatigue resistance, making them perfect for demanding applications. With a strong commitment to excellence and customer satisfaction, Neith Metals follows rigorous quality control standards to ensure that every product meets or surpasses global engineering and manufacturing specifications.
Alloy Steel AISI 4340 Bars and Rods are low-alloy steels that mainly consist of nickel (1.65–2.00%), chromium (0.70–0.90%), molybdenum (0.20–0.30%), carbon (0.38–0.43%), manganese (0.60–0.80%), and silicon (0.15–0.30%). This unique blend gives them remarkable hardenability and toughness. Their mechanical properties boast a tensile strength of 930–1080 MPa, a yield strength of 740 MPa, an elongation of 20%, and impressive impact resistance. AISI 4340 retains high strength even after heat treatment, providing excellent fatigue strength and wear resistance, making it a go-to choice for high-performance engineering components that face stress and dynamic loading.
