4340 belongs to the American standard high-strength alloy structural steel, which is made of high-quality carbon structural steel by appropriately adding one or several alloying elements.
What is 4340 chromoly steel?
4340 steel is a medium carbon nickel chromium molybdenum steel alloy with excellent tensile strength, toughness and fatigue resistance. Since the material is usually in the annealed condition, additional heat treatment (oil quenching and tempering, or normalizing and tempering) can produce parts with higher strength and fatigue resistance.
What are the advantages of 4340 chrome steel?
It has high strength, toughness, excellent hardenability and stability against overheating, good plasticity and heat resistance, uniform material, high working reliability, weldability, non-leakage, and simple steel structure production. Short construction period and good assembly.
What is 4340 chrome steel used for?
It is used as important quenched and tempered parts that require good toughness, high strength and large size, such as shafts of heavy machinery and high load, rotor shafts and blades whose operating temperature exceeds 400 °C, etc.
