Heat-resistant steel, which is excellent for the production of gas turbines, has recently been used much more often. There are several reasons for this. The fact is that recently interest in the industrial industry has grown significantly, and it has also become more common to use methods of high-temperature steel processing. Therefore, heat-resistant stainless steel 20x23n18, the characteristics of which are excellent for these purposes, has become popular.
Material Overview
If you take into account the characteristics, this steel can boast of such advantages as: the manufacturability of the material, increased ductility, high heat resistance. What is important is that the weldability of this metal is quite high. It is also worth noting that steel 20x23n18 belongs to the austenitic class of metal. The basis for this material are such two substances as nickel and iron.
Sheet steel is made of complex alloyed and austenitic alloy. It must have high resistance to any aggressive environmental influences. Atmospheric and soil moisture should also not have a significant effect on it. By itself, a steel heat-resistant sheet of the brand 20x23n18 is a very multifunctional and convenient material that allows you to use it in a variety of conditions. It is often used to make combustion chambers, the main requirement of which is high temperature resistance.
Steel classification
Most often, heat-resistant steels are used to make parts that can not be obtained in any other way. One of these parts was a blade for gas turbine engines. Most often, st 20h23n18, the characteristics of which allow it to withstand high temperatures well, suits perfectly. Other important details are also made from it.
Steel Processing Operations
In the industrial field today, several operations are used to produce elements for gas turbine engines. These include forging, grinding, machining, polishing, and precision casting. In order to go through all these stages of processing, it is necessary to use sufficiently high-quality steel. You can use a large number of different materials, but the characteristics of steel 20x23n18 indicate that it is most advantageous to use it, since it is most suitable for work. It can also be used in almost any climate. Thanks to all these qualities, it has become the most common in this area.
This steel is very resistant to the influence of high temperatures, and also survives sharp changes in this indicator. Most often it is used in engineering factories. It is made according to certain state standards, and therefore its quality is guaranteed.
Product Composition
Characteristics 20h23n18 metal due to its composition. High resistance to temperatures gives iron and nickel, which are part of the composition. Due to the presence of a certain amount of chromium in the composition, it was possible to achieve high resistance to corrosion, which makes it stainless. Very small, but still there is a carbon content in this steel grade. It is very important to note here that an excess of 0.2% of the carbon in the composition already indicates that the metal is of poor quality. In addition to these substances, which give certain characteristics of 20x23n18 metal, there are also such as phosphorus, sulfur, manganese.
Such a composition leads to the fact that it is possible to obtain not only heat-resistant material, but also steel, which is well moisture-tolerant. Nickel in the composition of the steel indicates that the material has a certain ductility. To obtain such characteristics for 20x23n18 steel, it must be manufactured in an arc furnace. In order to obtain high-quality material of this brand as a result, it is necessary to carry out a complex production process with temperature control at each stage.
Steel production
The production of this product is quite complicated. The initial stage should proceed at a temperature of 1180 ° C. The closer the process is to completion, the lower the temperature should be. It decreases until it reaches the limit of 900 ° C. With this indicator, the operation is completed. At this point, the deformation process ends and we can proceed to the next stage. There are several ways to heat treat a material. The first method is heating to a temperature of 1100-1150 ° C. Steel is hardened, after which it undergoes a cooling process in water, in oil or in air.
In the second method, the metal is heated to a temperature of 1160 ° C and increases to 1180 ° C. After that, you also need to cool the material in water. This will require at least four or five hours.
Steel use
The use of steel 20x23n18 with characteristics of high resistance to temperature, corrosion and other negative environmental influences determined the direction of use of the material. You can use this steel in almost any industry. It is used for the manufacture of aircraft parts. It is successfully used in the assembly of furnace equipment. Steel can withstand radiation exposure quite well, which led to its use in places where there is an increased indicator of this characteristic. For example, at nuclear power plants, because it is high-strength and has huge advantages.
