4140 Steel Properties
4140 steel is also referred to as DIN 1.7225 and JIS SCM440 steel. 4140 alloy steel type is a material with low notch precision. The impact toughness of this low-temperature steel is also at a high level. This material is typically used following quenching and annealing and shows no signs of brittleness. It also serves as a manufacturing process for high-strength fittings and parts that have other stretched components beneath impact loads.
The properties of 4140 steel, which serve a variety of purposes and are suitable in various applications, are essentially as follows;
- includes low alloy levels of chromium, molybdenum, and manganese. There is also an unalloyed type.
- The structure is resistant to abrasion and impact.
- It is a widely used material in the industry due to its versatility and usefulness.
- Depending on the amount of carbon in it, the stronger and more options for heat treatment.
- It also allows the use of oil to achieve high hardenability.
Its comprehensive mechanical properties are good, and it resists heat treatment well. Moreover, 4140 steel, a kind of medium-hardenable steel, is easily manufactured. The maximum use temperature is 427 degrees. Its application in tool bodies, turbine fasteners, shaping, and brake molds is evident in relation to these characteristics.
It is found that 1.7225 alloy tool steel can be machined effectively in its annealed state within the range of its machinability properties. Additionally good for shaping, 4140 steel has a high degree of hardness. Thus, shaping can be accomplished in the annealed state by employing conventional methods. However, since this material has a harder structure than other flat carbon steels, it is necessary to apply extra pressure or force. 4140 alloy steel can be welded with the use of advanced techniques. However, it is possible that the mechanical properties are affected when welding this material while it is heat treated. This is why heat treatment needs to be done following welding. After reaching a temperature of 845 degrees, the 4140 tool steel is quenched in oil. Then, by heating it to 913 degrees for an extended period of time and allowing it to cool naturally, it can be brought back to normal.
This steel is usually forged between 926 or 1205 degrees. The temperature of 816 or 1038 degrees can be used to perform hot workability. Not only can hot works be performed within these ranges, but cold works can also be performed by annealing the steel using conventional techniques. What should be done in the annealing process is to heat up to 800 to 850 degrees, keep the temperature equal until the section is longitudinal, and cool in the oven.
