High Toughness Astm 4340 Steel Pipes Stockists Supply - China

ASTM 4340 steel pipes are a type of high-strength, high-toughness low-alloy steel widely used in aerospace, petroleum industry, military and other fields.

When made into steel pipes, their high toughness and strength characteristics make them particularly suitable for environments with high pressure, impact or fatigue loads.

Heat treatment process:

Quenching and tempering (quenching + high-temperature tempering): obtain tempered troostite structure to achieve a balance between high strength (tensile strength can reach 1000-1200 MPa) and high toughness.

Secondary tempering: further improve impact toughness and reduce brittleness.

Application scenarios of high-toughness ASTM 4340 steel pipes

Oil and gas: used for drill collars, high-pressure pipelines, downhole tools, and withstand high pressure and hydrogen sulfide corrosion.

Aerospace: landing gear components, engine shafts, requiring high fatigue strength.

Military equipment: gun barrels, armored vehicle components, requiring impact resistance and ballistic performance.

Heavy machinery: hydraulic cylinders, transmission shafts, and withstand alternating stress.

If further customization of ASTM 4340 steel pipes is required (such as size, heat treatment process), it is recommended to provide specific working conditions requirements in order to optimize material properties.
