PZPS has successfully mastered the technology of hardening thin tape made of high-quality 65G structural steel 80 micrometers thick. Due to its unique properties, this tape is widely used for the manufacture of parts operating under load and precision instruments such as micrometers, watches and other measuring instruments.
Features of 65G steel
65G steel is one of the most common materials in mechanical engineering and the manufacture of industrial equipment. Its main benefits include:
- Strength and resilience. Due to the increased content carbon and manganese, 65G steel has an optimal balance of strength and elasticity. This makes it possible to manufacture products that can withstand significant loads, while maintaining plasticity and impact strength even under dynamic alternating loads.
- Hardness. 65G steel has a hardness in the range of 45—55 HRC. This provides it with high wear resistance and the ability to maintain its shape under the influence of external loads.
- Weldability. 65G steel is welded with restrictions. When welding, it is necessary to take into account the possibility of cracking and reducing the strength of the welded joint. This is due to the fact that structural changes occur due to the significant carbon content in the heat-affected zone.
- Processability. 65G steel is easy to cut, which makes it an ideal material for the manufacture of various parts.
To improve properties spring-spring 65G steel is widely used in heat treatment, which includes hardening and medium tempering. Hardening increases the strength and hardness of the material, and medium tempering reduces internal stresses and increases impact strength.
Thin tape heat treatment technology
Heat treatment thin metal tape is a process that requires special attention to detail and high accuracy. The complexity of this process is due to several factors that can affect the quality and properties of the final product.
- Uneven heating and cooling. Thin metal tape has a high thermal conductivity, which can lead to rapid heating and cooling in different parts of the tape. This, in turn, can cause uneven properties of the tape along its entire length, which is unacceptable when manufacturing measuring instruments that require high accuracy.
- The possibility of deformation of the tape under the influence of temperature and mechanical loads. Due to its thinness, the metal tape is easily deformed, which can lead to loss of shape or surface defects, which in turn will significantly reduce the quality of the final product and lead to non-compliance with quality standards.
- The complexity of controlling the heat treatment process. To ensure high product quality, it is necessary to control the temperature and processing time as accurately as possible. Even minor deviations can lead to undesirable changes in the properties of the tape, which can adversely affect the functionality of the devices manufactured.
Thanks to technologies developed by PZPS specialists, these difficulties were overcome: to ensure uniform heating and cooling, as well as strict adherence to all technological parameters. The result is a high-quality strip without deviations in properties along the entire length, which is ideal for the production of precision measuring instruments, such as micrometers.
Precision alloys with specified elastic properties
In addition to carbon spring grades 65G, 60S2A, 70, 70S2HA, PZPS pays special attention to the production of precision materials with specified elastic properties, including:
