DIN 41Cr4 and DIN 42CrMo4 materials have been widely used in automotive driving elements. Although 42CrMo4 is more expensive than 41Cr4, it is more preferable in terms of material properties. In this study, these two materials were heat treated by austenitizing in a continuous furnace at 850 °C and quenched in oil at 90 °C. After they were tempered at various temperatures, mechanical properties were determined for each tempering temperature. The material properties for both materials were compared with each other.

Heat Treatment:

• Forging:Heat to 1150°C Hold until uniform.Minimum forging temperature 850°C.
• Cool slowly in ashes or sand etc.
• Annealing:Heat to 830°C – 850°C. Cool in furnace.
• Normalising:Heat to 870°C – 900°C. Cool in still air.

Forging:

• Heat to 1150°C Hold until uniform.Minimum forging temperature 850°C.Cool slowly in ashes or sand etc.
• Annealing:Heat to 830°C – 850°C. Cool in furnace.
• Normalising: Heat to 870°C – 900°C. Cool in still air. Weld ability
• Readily welded in the annealed condition but avoid when possible if hardened and tempered due to the effect on the mechanical properties.
• Welding in the nitrided, flame or induction hardened condition is not recommended.

• It can be bent or formed by pressing or spinning in the annealed state.

Welding:

• AISI 4340 alloy steel can be welded using fusion or resistance welding methods.
• Preheat and post heat weld procedures are followed while welding this steel by established methods.

Heat Treatment:

• AISI 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:

• AISI 4340 alloy steel is annealed at 844°C (1550°F) followed by cooling the furnace.

Tempering:

• AISI 4340 alloy steel should be in the heat treated or normalized and heat treated condition before tempering.
• Tempering temperatures depend upon the desired strength level.

34CrNiMo6, it is one kind of Quench and tempering special CrNiMo steel material, characterized by high tensile strength and high toughness. It is suitable to the manufacture of components of maximum thickness equal to 120 mm meanly or strongly stressed and even with acomplicated geometry (shafts, camshafts, axles, levers, connecting rods, rocker arms, gear wheels). Advised austenitic grain dimension > 5 according to UNI 3245 (similar to ASTM E 112-82).

Normalizing:

• Normalizing temperature: 850.0°C

Forging:

• Hot forming temperature: 1100-900°C

Corrosion Resitance:

• This is a low alloy steel and rota corrosion resistant alloy
• Prolect: Ne coating shoud be used

Welding:

• The alloy can be fusion or resistance welded. Preheat and post heat wed procedures should be followed when welding this alloy by established methods.

Hardening:

• Harden from a temperature of 830-860°C followed by oil quenching.
• Quenching temperature in the end-quench test is 850°C

Stress Relieving:

• Stress relieving to remove machining stresses should be carried out by heating to approx. 650°C. holding for 1-2 hours at heat, followed by a, cooling
• This operation is perform. to r.uce distortion during heat treatment

Cold working:

• The VCH1,10150 alloy may be cold worked, in the annealed condion, by conventional methods and tooling. Chas good ductility.

Product Details:

4140 is a 1% chromium-molybdenum medium harden ability general purpose high tensile steel-generally supplied hardened and tempered in the tensile range of 850-1000 Mpa (condition T). 4140 available, which greatly increases feeds and/or speeds, while also extending tool life without adversely affecting mechanical properties. Pre hardened and tempered 4140 can be further surface hardened by flame or induction hardening and by nit riding. 4140 is used extensively most industry sectors wide range applications: Adapters, Arbors, Axle Shafts Bolts, Crankshafts, Connection Rods, Chuck Bodies, Collets, Conveyor Pins & Rolls, Ejector Pins, Forks, Gears, Guide Rods, Hydraulic Shafts & Parts, Lathe Spindles, Logging Parts, Milling Spindles, Motor Shafts, Nuts, Pinch Bars, Pins Various, Pinions, Pump Shafts, Rams, Sockets, Spindles, Sprockets, Studs, Tool Holders, Torsion Bars, Worms etc

Machinability:

• AISI 4140 alloy steel has good machinability in the annealed condition

Forming:

• AISI 4140 alloy steel has high ductility
• It can be formed using conventional techniques in the annealed condition.
• It requires more pressure or force for forming because it is tougher than plain carbon steels

Welding:

• AISI 4140 alloy steel can be welded using all conventional techniques
• However, the mechanical properties of this steel will be affected if it is welded in the heat treated condition, and post weld heat treatment should be performed.
