Steel-making Condition: EF, EF/EAF+LF+VD, EF/EAF+ESR
Delivery Condition:
Annealed , Quenched + Tempered
Surface Condition:
Black, Grinded, Peeled, Rough turned, Polished
MACHINABILITY:
1.6582 steel in the hardened and tempered as supplied condition is still regarded as being readily machinable and operations such as turning and drilling etc. can be carried out satisfactorily using machine manufacturers, recommendations for suitable tool type - feeds and speeds.
Welding:
Welding of 1.6582 steel in the hardened and tempered condition (as normally supplied), is not recommended and should be avoided if at all possible, as the mechanical properties will be altered within the weld heat affected zone. It is preferred that welding be carried out on 1.6582 steel while in the annealed condition, and that the work piece, immediately on cooling to hand warm, is then stress relieved at 640ºC- 660ºC 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 oC below the original tempering temperature (if known).

Heat Treatment:
Annealing: Heat to 800ºC - 850 ºC , hold until temperature is uniform throughout the section and cool in furnace.
Flame or Induction Hardening: 1.6582 steel can be further surface hardened by either the flame or induction hardening methods resulting in a case hardness in excess of Rc 50. Parts should be heated as quickly as possible to the austenitic temperature range (830ºC - 860ºC ) and required case depth followed by an immediate oil or water quench, depending upon hardness required, workpiece size/shape and quenching arrangements. Following quenching to hand warm, most components should be tempered between 150ºC - 200ºC to remove quenching stresses in the case. This will have little effect on case hardness.
Hardening: Heat to 830ºC - 860ºC, hold until temperature is uniform throughout the section, soak for 10 - 15 minutes per 25 mm section, and quench in oil, water, or polymer as required.
*Temper immediately while still hand warm.
Nitriding: 1.6582 steel can also be successfully nitrided, giving a surface hardness of up to Rc 60. Nitriding is carried out at 490ºC- 530ºC, followed by slow cooling (no quench) reducing the problem of distortion. Parts can therefore be machined to near final size, leaving a grinding allowance only. The tensile strength of the core is usually not affected since the nitriding temperature range is generally below the original tempering temperature employed. N.B. Nickel is inert to the action of nitrogen and in general resists its diffusion into steel. This can result in lower case hardness or longer nitriding cycle times for steels containing nickel such as 1.6582 steel.
Stress Relieving: Heat to 600ºC- 650 ºC, hold until temperature is uniform throughout the section, soak for 1 hour per 25 mm of section, and cool in still air.
Tempering: Reheat to 450ºC- 660ºCas required, hold until temperature is uniform throughout the section, soak for 1 hour per 25 mm of section, and cool in still air. N.B. Tempering should be avoided if possible within the range 250ºC - 450ºC due to temper brittleness.
Notes on Heat Treatment: Heating temperatures, rate of heating, cooling and soaking times will vary due to factors such as work piece size/shape also furnace type employed, quenching medium and work piece transfer facilities etc.
Application:
High voltage bolts and nuts, crankshafts, cam shafts, transmission axles, torsion bars, drive shafts, pump shafts, worm shafts, conveyor rollers, stems, pins, tie rods, clutch discs. Large-mass dies for hot stamping. 1.6582 Steel is widely used in the aerospace industry for structural parts of flaps assembly, fuselage and landing gear, propeller plane axles.
Product Description:
1.6582 Steel 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. A very popular, versatile steel. It can be heat-treated to produce a wide range of tensile strength in moderate sections.
