Where are the advantages of Stainless Steel Dowels compared to other materials?

The characteristics and structural design adaptability of our Stainless Steel Dowels have core advantages mainly in durability, stability and application scenarios compared to common materials such as carbon steel, aluminum alloy, plastic and copper. Let me explain in detail:

1. Our Stainless Steel Dowels have excellent corrosion resistance and can be used in harsh environments, with a much longer service life than carbon steel and other ordinary metals.

Our stainless steel contains alloy elements such as chromium and nickel, and a dense chromium oxide passivation film forms on the surface, which can resist the erosion of corrosive media such as moisture, acids, alkalis and salt spray. This is the most prominent advantage of our Stainless Steel Dowels:

Compared to carbon steel dowels: Carbon steel itself does not have rust resistance. Even if it is galvanized or chrome-plated, it is prone to rust after the coating wears off, causing loose connections. Therefore, it cannot be used in outdoor or humid environments (such as ships and bathroom equipment). Our dowels can be used for a long time in rain, seawater and weak acids without the risk of rust.

Compared to aluminum alloy dowels: Although aluminum alloy is light, it has weak corrosion resistance (especially prone to pitting corrosion in chloride-containing environments), and its main defect is low hardness, which makes it prone to deformation under long-term stress. This is where the advantage of our Stainless Steel Dowels comes in, as stainless steel can balance corrosion resistance and structural strength.

Compared to copper dowels: We all know that copper has some corrosion resistance, but its cost is higher than other materials. It is prone to oxidation and blackening in strong oxidizing agents, and its application scenarios are limited (only suitable for low-corrosion and decorative scenarios).

2. Our Stainless Steel Dowels have the dual advantages of high strength and high hardness, with strong load-bearing capacity and low risk of deformation and fracture.

The tensile strength, yield strength and hardness of our stainless steel are much higher than those of plastic and aluminum alloy, and even higher than ordinary low-carbon steel:

Plastic dowels are only suitable for light loads and non-impact scenarios. They are prone to aging and fracture under high temperatures or stress. Our stainless steel dowels can withstand mechanical impacts and high-frequency vibrations (such as motors and transmission equipment) without deformation risks. What about aluminum alloy dowels? They have low hardness and are prone to "plastic deformation" under heavy loads, resulting in reduced positioning accuracy. The hardness of our stainless steel can reach HB ≈ 150-200 (even higher after heat treatment), which can stably maintain dimensional accuracy. Next, let's talk about low-carbon steel dowels. They have insufficient strength, high hardness but poor toughness, and are prone to brittle fracture. Our products can balance strength and toughness, making them suitable for heavy loads and vibration in complex working conditions.

3. Our Stainless Steel Dowels have strong dimensional stability and high positioning accuracy, making them suitable for precision equipment.

The thermal expansion coefficient of our stainless steel dowels is between that of carbon steel and aluminum alloy, and they are less prone to dimensional drift due to humidity and temperature changes at room temperature, making it easy to control the processing accuracy. Plastic dowels are prone to water absorption and large thermal deformation, which can lead to increased positioning clearance over time and are not suitable for precision machinery (such as machine tools and electronic equipment). Other materials such as aluminum alloy dowels have a high thermal expansion coefficient. In alternating high and low temperature environments, their dimensional changes can affect connection accuracy. 

4. Our Dowels are hygienic, safe and non-magnetic, making them suitable for use in special scenarios such as food processing, medical and electronic fields. 

Our Stainless Steel Dowels have a smooth surface without pores, which makes them less likely to breed bacteria. They are also non-toxic and odorless, meeting food contact standards and can be used in food processing equipment and medical devices. Compared with plastic and copper, they are safer. Additionally, our 304 Stainless Steel Dowels and 316 Stainless Steel Dowels are non-magnetic and can be used in scenarios sensitive to magnetic fields; while carbon steel and ferromagnetic alloy pins can interfere with magnetic fields, and although aluminum alloy and copper are also non-magnetic, they lack sufficient strength.

5. Our products do not require rust prevention treatment, have a long service life and low maintenance costs.

Our products do not need additional rust prevention treatments such as galvanization or painting. After installation, they almost require no maintenance and have a service life 3 to 5 times longer than that of carbon steel pins, or even longer. In contrast, carbon steel pins need regular inspection of their rust-proof layer and replacement after wear, resulting in high long-term maintenance costs. Plastic pins are prone to aging and need frequent replacement, leading to even higher maintenance costs.
