What you will learn
• Describe the nitric acid production process and identify points where corrosion control is essential.
• Differentiate between the corrosion resistance of ferritic, austenitic, duplex, silicon-alloyed stainless steels, and nickel alloys in nitric acid environments.
• Explain how alloying elements such as chromium, molybdenum, silicon, and nickel affect corrosion performance.
• Identify conditions that promote intergranular corrosion, pitting, crevice corrosion, sigma-phase formation, or stress-corrosion cracking.
• Select appropriate materials for equipment such as absorbers, condensers, coolers, storage tanks, heaters, and distillation units.
• Evaluate when higher-alloyed materials (e.g., Alloy 20, C-22, G-30, 690, 825) are required for severe or mixed-acid conditions
• Apply alloy-selection principles to industrial sectors that use nitric acid, including fertilizer production, chemical processing, nuclear fuel reprocessing, and metal pickling.
