Threaded connections for high temperature applications are mostly made from high alloy steels. Since these alloys are very noble, they have almost no oxide layers which can protect them from seizure. Lubrication is absolutely essential to avoid seizure and also to not promote other failures of the connection such as stress corrosion cracking by elements that may be present in the lubricant. For these applications it is critical that lubricants be selected of the proper purity level to avoid failure of the alloys and seizure of the connection at high temperatures.
