Product Description

416 stainless steel precision dowel pins are specialized fasteners made from 416 stainless steel. These dowel pins are known for their high machinability, corrosion resistance, and dimensional accuracy, making them ideal for precision applications.

Material - 416 Stainless Steel:

The 416 stainless steel is a martensitic stainless steel known for its excellent machinability and corrosion resistance, particularly in mildly corrosive environments. It contains about 12% chromium, which provides its corrosion resistance, and can be heat-treated to enhance its mechanical properties.

Key Features of 416 Stainless Steel Precision Dowel Pins:

Precision Tolerance: These dowel pins are manufactured with tight dimensional tolerances, ensuring precise and consistent fits in mating parts. This precision is crucial in applications where alignment and accuracy are essential.

Corrosion Resistance: 416 stainless steel offers good resistance to corrosion in mildly corrosive environments. However, it is not as corrosion-resistant as some other stainless steel grades like 304 or 316, so it may not be suitable for highly corrosive applications.

Machinability: 416 stainless steel is highly machinable, making it easy to produce dowel pins with precise dimensions. This is particularly important for precision applications.

Heat-Treatable: 416 stainless steel can be heat-treated to improve its mechanical properties, such as hardness and strength.
