Alloy Steel AISI 4330, 4330V, 4145, 4150
-
Alloy steel 4330 is available in strips, sheets, plates, round and square bars, seamless and welded pipes & tubes, Forged & buttweld Fittings, flanges, fastener, flat rolled bars, Wire & valves.
AISI 4330 alloy steel is heated to 829°C (1525°F) and then quenched in oil. AISI 4330 alloy steel can also be heat treated to strength levels of 200 ksi or greater than 200 ksi, by first being normalized at 899°C (1650°F) before the heat treatment and then quenched to gain strength.

Principal Design Features AISI 4330 is a heat treatable steel alloy (for high strength) containing chromium, nickel and molybdenum. Carbon content is in the 0.30% range and in the heat treated condition the alloy has good toughness and fatigue strength as well as good strength. Alloy Steel 4330 Applications Applications are those that require a good combination of strength and impact resistance, such as gears, aircraft landing gear, axles or shafts for power transmission. Alloy Steel 4330 Machinability Machining is best accomplished with the alloy in the annealed, normalized and tempered condition. The alloy is much more difficult to machine in the strengthened (hardened) condition. Machinability in the high strength conditions can be only 15% to 25% that of the alloy in the annealed state. Alloy Steel 4330 Forming The formability is good, especially for sheet material in the annealed condition in which state it can be bent or formed by spinning. Bend radii should not be sharper than a 3t bend. Alloy Steel 4330 Welding 4330 may be welded by conventional methods. Preheat and post heat treatments should be used in accord with the recommended weld procedure for this alloy. The alloy may also be successfully joined by brazing. Alloy Steel 4330 Heat Treatment Hardening of 4330 alloy is done by heating to 1525 F and then oil quenching. If the alloy is to be heat treated to strength levels of 200 ksi, or greater, then it should first be normalized at 1650 F before being heat treated and quenched for strengthening. Alloy Steel 4330 Forging The alloy is forgeable in the range of 2200 F to 1800 F. Alloy Steel 4330 Hot Working Hot working may be done on this alloy, although usually not necessary because the alloy has good cold forming characteristics. Consult the alloy supplier for hot working information. Alloy Steel 4330 Cold Working Cold working capability is good and conventional methods may be used, Alloy Steel 4330 Annealing A full anneal may be done at 1500 to 1650 F followed by slow (furnace) cooling at a rate not in excess of 50 F per hour down to 600 F. From 600 F the alloy may then be air cooled. Alloy Steel 4330 Aging Not applicable to this alloy. Alloy Steel 4330 Tempering Tempering, following the Heat Treatment for hardening, varies depending upon the strength level desired. For the 260 - 280 ksi level use a tempering temperature of 425 to 500 F. For the lower strength 125 to 200 ksi level use 850 to 1175 F for tempering. At strength levels in the 220 to 260 ksi range tempering should NOT be done as it can result in degradation of impact strength. Alloy Steel 4330 Hardening The alloy harden by means of heat treatment and tempering. See "Heat Treatment" and "Tempering" -
