Description 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 36CrNiMo4 1.6511 EN24 817M40 AISI 4340 is also one kind ofnickel chromium molybdenum steels. 4340 alloy steel is generallysupplied hardened and tempered in the tensile range of 930 1080 Mpa.Pre hardened and tempered 4340 steels can be further surface hardened by flame or induction hardening and by nitriding.
4340 is a nickel-chromium-molybdenum alloy steel known for its toughness and its ability to attain high strengths in the heat-treated condition. It has very good fatigue resistance. AISI Alloy Steel 43404340 is a nickel-chromium-molybdenum alloy steel known for its toughness and its ability to attain high strengths in the heat-treated condition. It has very good fatigue resistance.
Alloy 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. Alloy Steel 4340 - Wingate Alloys IncAISI 4340 is a heat treatable, low alloy steel containing nickel, chromium, and molybdenum. The inclusion of nickel improves hardenability. Regarded industry-wide for its toughness, 4340 supplies high strength in the heat treated condition while still maintaining excellent fatigue strength over time.
