1. Hydrochloric Acid (HCl) Environment
The Nickle 200 Stud Bolt demonstrates good corrosion resistance in hydrochloric acid environments, especially under low concentration and low-temperature conditions. In 5% hydrochloric acid at 25°C, the corrosion rate is below 0.1 mm/year, showcasing excellent corrosion resistance. As the concentration and temperature of hydrochloric acid increase, the corrosion rate gradually rises. For example, in 10% hydrochloric acid at 25°C, the corrosion rate is 0.1 - 0.2 mm/year, while in 20% hydrochloric acid at 50°C, the corrosion rate increases to 0.8 - 1.5 mm/year. Under high concentration (> 20%) and high temperature (> 50°C) conditions, the corrosion rate significantly increases, making it unsuitable for long-term use.

2. Sulfuric Acid (H₂SO₄) Environment
The Nickle 200 Stud Bolt exhibits excellent corrosion resistance in dilute sulfuric acid environments. In 5% sulfuric acid at 25°C, the corrosion rate is below 0.1 mm/year. In 10% sulfuric acid at 25°C, the corrosion rate is 0.1 - 0.2 mm/year, while in 20% sulfuric acid at 50°C, the corrosion rate increases to 0.8 - 1.5 mm/year. Under high concentration (> 20%) and high temperature (> 50°C) conditions, the corrosion rate significantly increases. For instance, in 50% sulfuric acid at 50°C, the corrosion rate can reach 2.0 - 5.0 mm/year, making it unsuitable for long-term use.

4. Corrosion Resistance Mechanism
The corrosion resistance of the Nickle 200 Stud Bolt in non-oxidizing acidic media is primarily attributed to the following mechanisms:
- Passivation of High-Purity Nickel: Nickel forms a dense oxide layer in non-oxidizing acids, preventing further corrosion of the base material.

- Passivation of High-Purity Nickel: Nickel forms a dense oxide layer in non-oxidizing acids, preventing further corrosion of the base material.
- Low Impurity Content: Extremely low levels of impurities (e.g., sulfur, carbon, iron) reduce the risk of localized and intergranular corrosion.
- Uniform Corrosion: In non-oxidizing acids, the Nickle 200 Stud Bolt primarily exhibits uniform corrosion rather than localized corrosion, extending its service life.
5. Application Recommendations
- Low Concentration and Low Temperature: The Nickle 200 Stud Bolt performs exceptionally well in low concentration (≤ 10%) and low temperature (≤ 25°C) non-oxidizing acids, making it suitable for electronics, chemical processing, and food processing industries.
- Low Concentration and Low Temperature: The Nickle 200 Stud Bolt performs exceptionally well in low concentration (≤ 10%) and low temperature (≤ 25°C) non-oxidizing acids, making it suitable for electronics, chemical processing, and food processing industries.
- Moderate Concentration and Temperature: Under moderate concentration (10% - 20%) and temperature (≤ 50°C) conditions, the Nickle 200 Stud Bolt remains acceptable but requires regular corrosion inspections.
- High Concentration and High Temperature: Under high concentration (> 20%) and high temperature (> 50°C) conditions, the Nickle 200 Stud Bolt is not recommended. Consider using materials with higher corrosion resistance (e.g., Hastelloy or Inconel series).
6. Conclusion
The Nickle 200 Stud Bolt exhibits excellent corrosion resistance in non-oxidizing acidic media (e.g., hydrochloric acid, sulfuric acid, phosphoric acid), particularly under low concentration and low-temperature conditions. Its high purity and low impurity content ensure long-term stability and reliability. However, under high concentration and high-temperature conditions, the corrosion rate significantly increases, necessitating cautious use.
