Sulphide stress cracking of 17-4 PH for applications in oilfield components

What is it about?

This paper summarizes data demonstrating the susceptibility of high-strength and corrosion-resistant stainless steels to fracture when they are exposed to typical environments found in oil and gas production systems. The main reason for the failure, that generally occurs for loading conditions well below the material's capacity, is associated with the absorption of hydrogen.
