Summary of the lecture
A comprehensive guide offers a practical overview of how nickel-containing alloys perform in sulphuric acid environments across different concentrations. It explains the corrosion behaviour of carbon steels, stainless steels, nickel alloys, duplex grades, and other metals, and highlights how factors such as temperature, acid strength, flow conditions, and contaminants influence material selection. The guide also outlines alloy performance in concentrated, intermediate, and dilute sulphuric acid and summarises best practices for choosing corrosion-resistant materials in industrial processes involving sulphuric acid.
What you will learn:
- Differentiate sulphuric acid concentration ranges (dilute, intermediate, concentrated) and understand how each affects corrosion behaviour.
- Identify the corrosion characteristics of major alloy groups, including carbon steels, stainless steels, high-silicon alloys, nickel-based alloys, and duplex steels, when exposed to sulphuric acid.
- Explain the role of temperature, flow, and oxidation state in accelerating or reducing corrosion in sulphuric-acid handling equipment.
- Evaluate how contaminants such as chlorides, fluorides, nitrates, ferric ions, and cupric ions alter corrosion resistance and alloy performance.
- Recognize suitable materials of construction for processes involving sulphuric acid production, storage, transport, and processing.
- Understand the purpose and application of anodic protection in extending the service life of stainless steels in strong sulphuric acid.
- Compare the performance limits of specialty alloys such as Alloy 20, Alloy C-276, B-series Ni-Mo alloys, and high-silicon stainless steels across various operating conditions.
