Alloy Steel 4340 is another alloy known for superior mechanical properties. 4340 is a heat treatable, low alloy steel containing nickel, chromium and molybdenum. It is known for its toughness and capability of developing high strength in the heat treated condition while retaining good fatigue strength.
Combining strength and toughness with atmospheric corrosion resistance and wear resistance, 4340 alloy steel is commonly used in forged hydraulic and other machine applications as well as the aerospace industry. When you need a steel with high strength, that can operate under the most severe conditions, 4340 is the steel for you. 4340 Forged Steel Crankshafts - Competition Products4340 Forged Steel Crankshafts, CP 4340 Forged Steel Crankshafts, Scat 4340 Forged Steel Crankshafts, Scat Superlite 4340 Forged Crankshafts, Scat F43 Lightweight 4340 Steel

Mar 19, 2009 · Just wondering if anybody has worked with 4340 teel for knives or sharp tools. Now realising thecarbon content is only .40 but a low to mid 50s rockwell can be achieved through proper tempering. Just wanted to know what its like to work with for forging. Of course the nice salesman says it works AISI 4340 Alloy Steel (UNS G43400) - AZoMAISI 4340 alloy steel is heat treated at 830°C (1525°F) followed by quenching in oil. Forging. AISI 4340 alloy steel is forged at 427 to 1233°C (1800 to 2250°F). Cold Working. AISI 4340 alloy steel can be cold worked using all conventional methods in the annealed condition. It has high ductility. Annealing
4340 Steel Heat Treatment. AISI 4340 alloy steel is heat treated at 830°C (1525°F) followed by quenching in oil. Flame or Induction Hardening. As mentioned above, pre-hardened and tempered 4340 steel bars or plates can be further surface hardened by either the flame or induction hardening methods resulting in a case hardness in excess of Rc 50. AISI Alloy Steel 43404340 alloy steel General Characteristics of Alloy Steel 4340 4340 is a nickel-chromium-molybdenum alloy steel known for its toughness and its ability to attain high strengths in the heat-treated condition.
