4340 Steel Round Bar Sheet Plate Heat Treatment and Process Stress Relieving For pre-hardened steel stress relieving is achieved by heating steel 4340 to between 500 to 550°C. Heat to 600 °C – 650 °C, hold until temperature is uniform throughout the section, soak for 1 hour per 25 mm section, and cool in still air. Cold Working AISI 4340 alloy steel can be cold worked using all conventional methods in the annealed condition. It has high ductility. Annealing A full anneal may be done at 844°C (1550 F) followed by controlled (furnace) cooling at a rate not faster than 10°C (50 F) per hour down to 315°C (600 F). From 315°C 600 F, it may be air cooled. Tempering AISI 4340 alloy steel should be in the heat treated or normalized and heat treated condition before tempering. The tempering temperature for depends upon the strength level desired. For strength levels in the 260 – 280 ksi range temper at 232°C (450 F). For strength in the 125 – 200 ksi range temper at 510°C (950 F). And don’t temper the 4340 steels if it is in the 220 – 260 ksi strength range as tempering can result in degradation of impact resistance for this level of strength. Tempering should be avoided if possible within the range 250 °C – 450 °C due to temper brittleness. 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 4340 steel parts should be heated as quickly as possible to the austenitic temperature range (830 °C – 860 °C) and required case depth followed by an immediate oil or water quenching, depending upon hardness required, workpiece size/shape and quenching arrangements. Following quenching to hand warm, tempering at 150°C – 200°C will reduce stresses in the case with minimal effect on its hardness. All de-carburized surface material must first be removed to ensure the best results. Nitriding Hardened and tempered 4340 alloy steel can also be nitrided, giving a surface hardness of up to Rc 60. Heat to 500°C – 530°C and hold for sufficient time (from 10 to 60 hours) to develop the depth of the case. Nitriding should be followed by slow cooling (no quench) reducing the problem of distortion. The nitrided grade 4340 materials can therefore be machined to near final size, leaving a small grinding allowance only. The tensile strength of the 4340 steel material core is usually not affected since the nitriding temperature range is generally below the original tempering temperature employed. Surface hardness achievable is 600 to 650HV. Machinability It can be machined using all conventional techniques. Machining process can be performed in the annealed or normalized and tempered conditions. Welding Welding of steel in the hardened and tempered condition (as normally supplied), is not recommended and should be avoided if at all possible, because of the danger of quench cracking, as the mechanical properties will be altered within the weld heat affected zone. If welding must be carried out, pre-heat to 200 to 300°C and maintain this while welding. Immediately after welding stress relieve at 550 to 650°C, prior to hardening and tempering. If welding in the hardened and tempered condition is really necessary, then the work piece, immediately on cooling to hand warm, should be if possible stress relieved at 15 °C below the original tempering temperature.

4340 steel is nickel-chromium-molybdenum alloy steel. It will get high strength after the heat treat. And it has good toughness, fatigue resistance, impact toughness and etc. Its equivalent grade is JIS SNCM439 and DIN 1.6511 / DIN 1.6582. The 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. It is used widely in the transmission components of heavy chemical machinery. Different sections of each part of the casting which cause the temperature difference stress and phase transformation stress. If you can’t get their laws and characteristics, you can’t take the right rational processes. The consequence is that there is a risk of cracking the casting during the casting or heat treatment. So the control of chemical composition and the choice of the heat treatment process for the casting are really important. 1.6511 Steel Application 4340 alloy steel is used to manufacture large and medium-sized plastic molds that require high strength and toughness. And it is used for making important quality controlling parts with good toughness, high strength, and large size, such as heavy machinery and high load shafts, dia of turbine shafts is larger than 250mm, helicopter rotor shafts, turbojet turbine shafts, blades, high-load transmission parts, crankshaft fasteners, gears and etc. After nitriding, it also can be used to make important parts for special performance requirements. And it will be a great material for high strength and good plasticity parts after low-temperature tempering or isothermal quenching.
