AISI 4340 alloy steel is a medium carbon nickel-chromium molybdenum alloy steel that creates an excellent combination of ductility, toughness, and strength after heat treating. It has good shock and impact resistance as well as wear and abrasion resistance in the hardened condition. AISI 4340 Steel - JIS SNCM439 - DIN 1.6563 - Songshun SteelThe properties and composition of 4340 steel round bar sheet plate as below. It is an alloy structural grade which used by the SAE International(SAE), and it is chrome-nickel low alloy steel. 4340 steel round bar sheet plate will get high tensile strength, hardness and toughness after heat treatment. AISI 4340 Steel, oil quenched 855°C (1570°F), 230°C (450°F AISI 4340 has a favorable response to heat treatment (usually oil quenching followed by tempering) and exhibits a good combination of ductility and strength when treated thusly. Uses include piston pins, bearings, ordnance, gears, dies, and pressure vessels.

Aircraft Alloy Steel AISI 4340 / E-4340 - Aircraft MaterialsAlloy E 4340 is a widely used deep-hardening constructional steel. Due to E-4340's high alloy content it obtains a uniformed hardness by heat treatment. The high fatigue strength makes E4340 ideal for highly stress parts as it maintains it's strength and hardness at elevated temperatures.
