The circlip made of SKD11 material has become the ideal choice for precision manufacturing, molds, and industrial equipment fields, thanks to its outstanding performance and sophisticated craftsmanship. Its core material, SKD11, is a high-carbon and high-chromium alloy tool steel. Through optimized formulation and smelting processes, it possesses an ultra-high hardness of 60 - 62 HRC, excellent toughness due to uniformly distributed carbides, and remarkable hardenability, ensuring long-term stable operation under complex working conditions. The production process adopts rigorous techniques: forging refines the grain structure, spheroidizing annealing improves machinability, quenching and tempering precisely balance hardness and toughness.
Additionally, technologies such as CNC machining and wire electrical discharge machining are employed to strictly control dimensional accuracy. Optional surface treatments like TiCN coating and ion sulfurization can be customized to enhance wear resistance. During use, it is essential to adhere to heat treatment specifications, pay attention to protection during machining, store it in a dry environment, and use professional tools for assembly to ensure stability. This circlip is widely applicable to precision molds (such as IC stamping dies, cold-forming dies for automotive leaf springs), wear-resistant tools, and high-precision equipment in the semiconductor industry. In harsh environments involving high stress, high-frequency impacts, and high-temperature vibrations, its service life and stability far exceed those of circlips made from ordinary materials, providing a reliable "locking + positioning" guarantee for the efficient operation of equipment.

Product Introduction of Circlip Made of SKD11 Material
I. Material Analysis
SKD11 is a high - carbon and high - chromium alloy tool steel. Through optimized alloy formulation and smelting process, it has the following characteristics:
- High Hardness: After heat treatment, the hardness can reach 60 - 62 HRC, with strong wear resistance and deformation resistance, ensuring the long - term stable operation of the circlip.
- Strong Toughness: The carbide is uniformly distributed, with both toughness and compression resistance, suitable for complex working conditions, and not easy to crack or break.
- Good Hardenability: It is easy to be hardened during heat treatment, and the hardness of the core and the surface is uniform, with excellent dimensional stability, meeting the requirements of high - precision assembly.
II. Processing Technology
1. Forging: Precisely control the heating and forging parameters to refine the grains, eliminate internal defects, and improve the material density and comprehensive performance.
2. Spheroidizing Annealing: Insulate at 790 - 810 °C and then cool slowly at 720 - 740 °C to improve the machinability and lay the foundation for subsequent processing.
3. Quenching + Tempering: After austenitizing at 1000 - 1030 °C, cool in oil/high - pressure gas quenching, and then temper at 180 - 250 °C (for precision parts) or 500 - 550 °C (for parts with high toughness) to balance hardness and toughness and stabilize the size.
4. Precision Forming: Use CNC machining, wire cutting and other processes to strictly control the dimensional accuracy of the circlip (such as the opening gap, diameter tolerance) to ensure the assembly adaptability.
5. Surface Treatment: Optional TiCN coating (increasing the surface hardness to over 3000 HV+), ion sulfurizing (reducing the friction coefficient), etc., to enhance wear resistance and friction - reducing performance.
III. Precautions
1. Heat Treatment Specification: Strictly follow the parameters of temperature, holding time and cooling rate to avoid problems such as insufficient hardness, deformation and cracking. It is recommended to be operated by a professional heat treatment factory.
2. Processing Protection: Use cemented carbide tools for machining, and pass cooling liquid during cutting; select diamond grinding wheels for grinding, and control the feed rate to prevent burning and chipping.
3. Storage Environment: Store in a dry and ventilated place to avoid rusting due to moisture; apply anti - rust oil for long - term storage, and clean the surface before use.
4. Assembly Points: Use tools such as circlip pliers for operation, and avoid violent installation; after assembly, check the opening elasticity and the matching state with the groove to ensure no jamming or loosening.
IV. Application Scenarios
- Precision Molds: Such as IC lead frame stamping dies, cold - forming dies for automobile leaf springs, which can withstand high stress and high - frequency impact, and the service life of the cutting edge/clamping part is long (several times longer than that of ordinary materials).
- Cutting/Wear - Resistant Tools: In scenarios such as electronic component shearing and powder metallurgy compacting, it is resistant to wear and chipping, ensuring processing accuracy and efficiency.
- Industrial Equipment: In high - precision machinery and semiconductor equipment, as a positioning and locking component, with high stability, it is suitable for harsh working conditions (such as high - temperature and vibration environments).
The circlip made of SKD11 material, with excellent hardness, toughness and processing accuracy, provides a reliable "locking + positioning" solution for the fields of precision manufacturing, molds, and industrial equipment, and helps equipment operate efficiently and stably.
