Corrosion Resistance of DIN W.Nr.2.4060 Bolt  
Nickel 200 is a commercially pure nickel material, and its high corrosion resistance is primarily attributed to its high nickel content (≥ 99.6%) and excellent chemical stability.  
 
1. Corrosion Resistance in Acidic Media  
The DIN W.Nr.2.4060 Bolt exhibits excellent corrosion resistance in non-oxidizing acidic environments, as detailed below:  
Hydrochloric Acid (HCl):  
The Bolt shows good corrosion resistance to low-concentration hydrochloric acid at room temperature. However, the corrosion rate increases in high-concentration or high-temperature hydrochloric acid. It is typically suitable for environments with hydrochloric acid concentrations below 15%.  

 
Sulfuric Acid (H₂SO₄):  
At room temperature, the Bolt demonstrates excellent corrosion resistance to dilute sulfuric acid (concentrations below 60%). However, its corrosion resistance significantly decreases in high-concentration or high-temperature sulfuric acid.  

 
Phosphoric Acid (H₃PO₄): 
The Bolt exhibits good corrosion resistance in phosphoric acid environments, making it suitable for phosphoric acid media with concentrations below 85%, especially at room or low temperatures.  

 
Acetic Acid (CH₃COOH):  
In acetic acid environments, the Bolt demonstrates excellent corrosion resistance, making it suitable for acetic acid media of various concentrations and temperatures.  
 
2. Corrosion Resistance in Alkaline Media  
The DIN W.Nr.2.4060 Bolt exhibits excellent corrosion resistance in alkaline environments, as detailed below:  
Sodium Hydroxide (NaOH) and Potassium Hydroxide (KOH):  
Nickel 200 has extremely high corrosion resistance to strong alkalis such as sodium hydroxide and potassium hydroxide, maintaining good performance even at high temperatures and concentrations. The Bolt performs exceptionally well in strong alkaline environments.  

 
Ammonium Hydroxide (NH₄OH):  
In ammonium hydroxide environments, the Bolt demonstrates excellent corrosion resistance, making it suitable for ammonium hydroxide media of various concentrations and temperatures.  
 
3. Corrosion Resistance in Salt Media  
The DIN W.Nr.2.4060 Bolt exhibits good corrosion resistance in salt environments, as detailed below:  
Chlorides (Cl⁻):  
In chloride environments, the Bolt shows high corrosion resistance, particularly at low and moderate temperatures. However, localized corrosion (such as pitting or crevice corrosion) may occur in high-temperature, high-concentration chloride environments.  

 
Sulfates (SO₄²⁻):  
The DIN W.Nr.2.4060 Bolt demonstrates good corrosion resistance to sulfates, making it suitable for sulfate media of various concentrations.  
 
4. Corrosion Resistance in High-Temperature Environments

Oxidizing Atmospheres:  
In oxidizing atmospheres, the DIN W.Nr.2.4060 Bolt forms a dense oxide layer on its surface, protecting the base material from further oxidation. Its maximum service temperature can reach 315°C.  

 
Reducing Atmospheres: 
In reducing atmospheres, the DIN W.Nr.2.4060 Bolt exhibits good corrosion resistance, but care should be taken to avoid contact with sulfides to prevent sulfide corrosion.  
 
5. Corrosion Resistance in Marine Environments  
The DIN W.Nr.2.4060 Bolt demonstrates excellent corrosion resistance in marine environments, as detailed below:  
Seawater:  
The DIN W.Nr.2.4060 Bolt shows high corrosion resistance to seawater, making it suitable for marine engineering equipment such as ships and offshore platforms.  

 
Salt Spray: 
In salt spray environments, the DIN W.Nr.2.4060 Bolt exhibits good corrosion resistance, making it suitable for equipment in coastal areas.  
 
6. Corrosion Resistance in Special Corrosive Environments  
Organic Media:
