The Importance of Restricting Ni+Mn in P91 and P92 Welding

In the world of metallurgy and welding, certain alloy steels are revered for their exceptional high-temperature properties, among them being P91 and P92. These alloys find extensive use in power plants, industrial boilers, and other high-temperature applications. However, there’s an interesting restriction imposed on these materials: the combined content of Nickel (Ni) and Manganese (Mn) […]

Taper Transition Requirement for Dissimilar Wall Thickness

In this article we will discuss about the taper transition requirement for dissimilar thickness as per ASME Section VIII Division 1: What is Taper Transition? Transition is formed by removing the material by grinding or machining from the thicker material section to match it with the thinner section’s thickness. When Taper Transition required? Taper transition
