How are the rivets of 3/8" SQUARE TOOTH CHAINSAW CHAIN ​​hardened with high precision? How does this hardening process affect the friction load and bearing strength of each part of the chain saw chain?

How are the rivets of the chain saw chain hardened with high precision?
The high-precision hardening of the rivets of 3/8" SQUARE TOOTH CHAINSAW CHAIN ​​usually involves the following steps:
Material selection: First, select rivet materials suitable for hardening, which usually have good mechanical properties and machinability.
Heat treatment: The rivet is heated to a certain temperature to change its internal microstructure and properties. This process may include multiple stages such as heating, insulation and cooling to ensure that the rivet reaches the required hardness and strength.
Surface hardening: On the basis of heat treatment, the surface of the rivet is further hardened by carburizing, nitriding or surface quenching. These treatments can enhance the hardness and wear resistance of the rivet surface while maintaining the toughness inside.
Precision machining: The hardened rivets need to be precision machined to ensure that their size and shape meet the design requirements. This may include grinding, polishing and other processes to improve the surface finish and precision of the rivet.
How does this hardening process affect the friction load and bearing strength of each part of the 3/8" SQUARE TOOTH CHAINSAW CHAIN?
Hardening has a significant impact on the friction load and bearing strength of each part of the chain saw chain:
Improved friction load capacity: The hardened rivet surface has higher hardness and wear resistance, so it can better resist the friction and wear generated during use. This helps to reduce the performance degradation and failure rate of the chain saw chain caused by friction.
Enhanced bearing strength: Hardening not only increases the hardness of the rivet, but also enhances its internal strength and toughness. This allows the rivet to better withstand the tension and compression generated by the chain saw chain during operation, thereby improving the overall bearing strength of the chain saw chain.
Optimized load distribution: The hardened rivet can better cooperate with other chain links to form a more stable connection structure. This helps to optimize the load distribution of the chain saw chain during operation and reduce damage and failures caused by uneven load.
