In order to ensure optimal performance and safety, special steel used in the chemical industry must satisfy specific criteria. Some of the essential requirements for special steel in this industry comprise:
1. Corrosion resistance: The steel must exhibit high resistance to corrosion as it will be exposed to various aggressive chemicals and corrosive environments. This necessitates the steel's ability to endure the corrosive effects of acids, alkalis, and other chemicals commonly used in the industry.
2. High temperature resistance: The steel should demonstrate excellent heat resistance to endure high operating temperatures frequently encountered in chemical processes. This is crucial to prevent degradation or loss of strength when subjected to elevated temperatures.
3. Mechanical strength: Special steel used in the chemical industry should possess superior mechanical strength to withstand the high stress and pressure that may arise during chemical processes. It should maintain its structural integrity even under challenging conditions.
4. Fatigue and stress resistance: The steel must exhibit good resistance to fatigue and stress as it will be subjected to cyclic loading and pressure variations during operation. This is vital to ensure the longevity and reliability of the steel in the chemical industry.
5. Pitting and crevice corrosion resistance: Special steel should be resistant to pitting and crevice corrosion, which can occur in areas exposed to stagnant or low-velocity corrosive media. Pitting and crevice corrosion can lead to localized damage and failure of the steel, making resistance to these types of corrosion indispensable.
6. Low impurity content: Special steel used in the chemical industry should contain minimal impurities to minimize the risk of contaminating the processed chemicals. Impurities can react with the chemicals or cause undesired reactions, potentially resulting in product quality issues or safety hazards.
7. Easy cleanability: The steel should possess a smooth surface and be easily cleanable to prevent the accumulation of contaminants or fouling. This is crucial to maintain the purity of the processed chemicals and ensure efficient equipment operation.
By meeting these specific requirements, special steel used in the chemical industry can endure harsh conditions and corrosive environments while preserving its structural integrity, performance, and safety.
