 Application 


astm 4340 steel sheet used in aerospace

AEROSPACE

ASTM 4340 steel plate is a high hardenability oil-quenched steel with an average carbon content of 0.40% to 0.42%. It is specially used to manufacture large shafts and shaft parts in aviation parts. It is often used to manufacture aircraft parts, such as engine parts, bearings, gears, connecting rods, and turbine blades. Its high strength and wear resistance enable it to withstand stress under high loads and high temperatures.
