According to the Nitrided ferro chrome products we know in daily life, they are generally used in the steel industry, aerospace industry, and automobile manufacturing industry to increase the strength, hardness, and corrosion resistance of steel, and can instand of metal nickel , thereby saving certain production costs.
The content of our common ferrochrome nitride is Cr: 60-70% C: 0.03-0.1% max, Si: 1.5% max; S: 0.05% max; P: 0.05% max, N: 5-10%.
However, different N contents have different requirements for production processes, raw material requirements, production costs, product performance, etc., so I would like to share the requirements for different N contents to help us choose a more appropriate content.
Ferrochrome nitride the nitrogen content is 5-6%
5 – 6% nitrogen content: The nitrogen content specified in the product standard of ferrochrome nitride in my country is 3.0% – 5.0%, which can be achieved relatively stably by using the solid-state nitriding production process of vacuum resistance furnace. This process is relatively mature, with less control difficulty, and the requirements for equipment and process parameters in the production process are relatively less stringent.
Ferrochrome nitride the nitrogen content is 8-9%
8 – 9% nitrogen content: To achieve this nitrogen content range, more precise control of the production process is required. It may be necessary to optimize the parameters such as nitrogen gas intake, temperature, and holding time on the basis of solid-state nitriding, or to adopt some improved nitriding technologies, such as plasma nitriding, to increase the diffusion rate of nitrogen atoms and the solid solubility in ferrochrome, and the production difficulty has increased.
Ferrochrome nitride the nitrogen content is 10%
Nitrogen content above 10%: The production difficulty has increased significantly. It is usually necessary to adopt special production processes or equipment, such as the use of higher purity raw materials, more advanced vacuum melting equipment, and precise nitrogen atmosphere control technology. At the same time, the control accuracy of parameters such as temperature, pressure, and time in the production process is extremely high, and any slight fluctuation in any parameter may affect the stability of the nitrogen content and product quality.
Raw material requirements for the production of FeCrNwith different nitrogen contents
FeCrN The nitrogen content is 6%
6% nitrogen content: General low-carbon ferrochrome raw materials can meet the requirements, and the requirements for raw material purity and composition uniformity are relatively low. It is only necessary to ensure that the impurity content in the raw materials is within a certain range to avoid affecting the nitriding effect and product quality.
The Nitrogen Content is 8-9% of Ferrochrome nitride
8 – 9% nitrogen content: The purity requirements for raw materials have increased, and the impurity content in the raw materials needs to be more strictly controlled, especially for elements that can affect nitrogen absorption and solid solution, such as oxygen, silicon, etc., which need to be more finely controlled. The raw materials may need to be pretreated to reduce the impurity content, improve the purity of the raw materials, and ensure the smooth progress of the nitriding process.
The Nitrogen Content is 10% of Ferrochrome nitride
Nitrogen content above 10%: The selection and treatment of raw materials are more critical. High-purity ferrochrome raw materials are required, and the composition uniformity of the raw materials is extremely high. Special raw material pretreatment processes, such as vacuum degassing, deep deoxidation, etc., may be required to remove harmful impurities and gases in the raw materials to create favorable conditions for the formation of high nitrogen content.
Production cost of different Nitrogen content in Nitrided ferrochrome producing
The ferrochrome nitride with the nitrogen content is 5-6%
5-6% nitrogen content: The production process is mature, the equipment requirements are relatively low, and the raw material cost is relatively low. Therefore, the production cost is relatively low, and the product has certain price competitiveness in the market. It is suitable for the production of ordinary nitrogen-containing steel and other fields that do not require particularly high nitrogen content.
The ferrochrome nitride with the nitrogen content is 8-9%
8-9% nitrogen content: Due to the increased difficulty of the production process, more energy and time are required to control the process parameters. At the same time, the requirements for raw materials are increased, resulting in an increase in raw material costs, so the production cost is relatively high. However, its product performance is better than that of 5-6% nitrogen ferrochrome nitride, which is suitable for fields with high requirements for steel performance, such as high-end stainless steel products, special mechanical parts, etc.
The ferrochrome nitride with the content is 10%
10% or more nitrogen content: The production cost increases significantly. In addition to the high cost of raw materials and the increase in energy consumption and time costs caused by the complex production process, it may also be necessary to invest more R&D and technical support costs to solve technical problems in the production process. In addition, the qualified rate of the product may be relatively low, which will also increase the production cost. Therefore, its product price is relatively high, and it is mainly used in high-end fields with extremely demanding requirements for steel performance, such as aerospace, defense and other high-precision fields.
The different nitrogen content Product performance and application
- 5 – 6% nitrogen content: can improve the strength, hardness and corrosion resistance of steel to a certain extent, suitable for general nitrogen-containing steel production, can partially replace precious metal nickel, reduce production costs, and is widely used in architectural decoration, kitchenware, general machinery manufacturing and other fields that do not require particularly high steel performance.
- 8 – 9% nitrogen content: with the increase of nitrogen content, the strength, hardness and corrosion resistance of steel are further improved, which can meet higher requirements of industrial applications. For example, in the fields of engine parts, transmission system parts in automobile manufacturing, as well as mold manufacturing, electronic information, etc., it can be used to manufacture parts that withstand higher loads and harsher working environments.
- 10% or more nitrogen content: can make steel obtain extremely high strength, hardness and corrosion resistance, while also improving the toughness and fatigue resistance of steel. It is suitable for fields such as aerospace, national defense, and high-end medical equipment that have extremely strict requirements on material performance, and can meet the high performance requirements of materials in these fields under extreme conditions.
