What is 42CrMo4 (4140) (1.7225) Steel?

42CrMo4 alloy quenched steel, also known as 4140 steel or 1.7225 steel, is a common chromium-molybdenum steel with high density, and high hardenability, usually used after tempering. 42CrMo4 quenched steels have better performance than 34CrMo4 steels due to higher carbon and chromium content. 4140 steel has higher strength and hardenability in terms of its properties. The properties of AISI 4140 steel include high strength and good low-temperature impact toughness. Therefore, its machinability is high.

Although it is more expensive than 41Cr4 steel, 4140 is preferred regarding material properties. 42CrMo4 alloyed engineering steel materials are widely used in automotive drive elements.

Engineering steel 42CrMo4 material has only limited weldability. Preheating to 200-300°C is highly recommended. The upper limit should not be exceeded due to the risk of deterioration of the chrome layer.

Sağlam Metal is able to supply you with a wide range of premium quality 42CrMo4 alloy steel materials.

What are the Mechanical Properties of 42CrMo4 (4140) (1.7225) Steel?

You can review the mechanical properties of 42CrMo4 (4140) quenched steel from the PDF file in the "Technical Details" tab. All mechanical and material properties of 42CrMo4 (4140) quenched steel are specified in this section.

What is the Hardness of 42CrMo4 (4140) (1.7225) Quenched Steel?

The hardness of 4140 quenched steel is maximum of 241 HB.

Where is 42CrMo4 (4140) (1.7225) Alloy Steel Used?

4140 (42CrMo4) alloy steel is widely used for engineering steel purposes, such as various machinery, automobile, mining spare part, gear wheel of engines, drive gears of superchargers, connecting rods, parts for powertrain applications, cold formed fasteners, it is frequently used in areas such as shafts, gears, oil exploration works.

How is 42CrMo4 (4140) (1.7225) Quenched Steel Hardened?

42CrMo4 steel is slowly heated to 880°C. 42CrMo4 steel rising to this temperature can be quenched in oil or water. 42CrMo4 steel can be tempered as soon as it reaches room temperature (20°C). After the tempering process, it is heated evenly to the appropriate temperature of 560°C. After the processes are completed, the 42CrMo4 material is taken from the furnace and cooled in the air.

In general, the higher the hardness, the harder it is to machine. Therefore, the hardness is not high for the unheated-treated 1.7225 material and is relatively easy to machine. After soft annealing, 42CrMo4 steel is easier to machine.

The hardness of 4140 Quenched material after heat treatment and tempering is generally 300HB. Such hardness is still very common for machining. As long as you choose a reasonable speed and tool, you can still safely machine these hardnesses.

What is the Price of 42CrMo4 (4140) (1.7225) Quenched Steel?
