Alloy Steel Dowel Pins
Weight Range ： 0.5g–500kg
Dimensional tolerance ： ±0.05mm
Alloy Steel Dowel Pins are manufactured from high quality alloy steel. Products strictly comply with international standards such as DIN 6325 and ISO 8734. After quenching and tempering heat treatment, its hardness remains stable in the range of HRC 50-64. This characteristic gives the product excellent mechanical strength and wear resistance. They can withstand high mating and unmating frequencies and sustained vibration loads. Therefore, it is widely used in precision molds, heavy machinery and automated production lines. It provides stable and reliable positioning function for key components.
During the manufacturing process, corrosion protection and surface quality are primary considerations. Thanks to the precision grinding process, the surface finish of the product reaches Ra ≤ 0.8 μm. This not only improves fit accuracy, but also effectively reduces assembly friction. Products can be surface treated with chrome plating, zinc plating, phosphating or blackening. These treatments significantly improve the corrosion resistance of the product. In addition, certain treatments can improve the wear resistance and surface hardness of the product. This allows the product to adapt to complex working conditions such as humid environments, chemical media or specific aesthetic requirements.

Benefits
Excellent strength and wear resistance
Alloy steel locating pins are quenched and tempered. Its hardness can reach HRC 60-64. Therefore it has extremely high wear resistance. It effectively resists repeated plugging and unplugging and vibration wear. Compared with ordinary medium carbon steel positioning pins, the service life is increased several times. It is especially suitable for high-frequency scenarios such as automation equipment. This significantly reduces replacement frequency and maintenance costs. This ensures long-term stable operation of the equipment.
Excellent shear strength
Alloy steel positioning pins contain elements such as chromium and molybdenum and are heat treated. Allowing it to withstand high shear forces without breaking. Take, for example, an AISI 4140 pin with a diameter of 10 mm. Its shear strength is approximately 78 kN. Suitable for heavy machinery, molds and transmission systems. It can reliably fix parts and prevent lateral displacement. Ensure the safety and integrity of the overall structure.
Good surface treatment adaptability
It provides a solid base for a variety of surface treatments. Can be blackened, phosphated, galvanized or chromed. Phosphating film thickness is usually 5-20 microns, which enhances wear resistance and oil storage. After treatment, the salt spray corrosion resistance time can reach 72 to 500 hours. This greatly broadens its application scope in various environments.
Broad size range and standardization advantages
The manufacturing standards of alloy steel positioning pins cover an extremely wide range of sizes, from micro pins weighing only 0.5 grams for precision instruments to giant pins weighing more than 500 kilograms for heavy hydro turbines or wind turbines. This full range of standardized production means that engineers can directly quote international standard numbers such as DIN and ISO when designing, and obtain the required parts without customization, which greatly shortens the design cycle and ensures the interchangeability and supply convenience of spare parts worldwide.
