Low-temperature bolting
Low-temperature bolting is a service category whose material and mechanical properties must be selected for the minimum design temperature and applicable toughness requirements. The general product name does not establish one grade, alloy, or temperature limit. The actual material specification, heat treatment, required testing, coating, and compatibility of the nut and other assembly components must be explicit in project documents.
Application and duty
Low-temperature bolted joints after grade and project toughness requirements are specified
