Heavy Duty AISI/SAE 4340 Alloy Steel Bar

AISI 4340 is a widely utilized alloy steel known for its high strength, toughness, excellent wear resistance, and corrosion resistance. Its moderate carbon content contributes to good machinability and weldability. Furthermore, the inclusion of appropriate amounts of chromium, nickel, and other elements enhances its overall performance. Notably, it exhibits commendable toughness and ductility, maintaining reliable performance in both high and low-temperature environments. Due to its outstanding physical and mechanical properties, 4340 steel bars find extensive use in equipment manufacturing for corrosive environments such as in the petroleum, chemical industry, and maritime applications.
