Alloy steel pipe

Alloy steel pipe is a broad class of steel tubular products whose alloy composition is controlled to obtain a defined combination of engineering properties. The name does not identify one grade or a universal pressure-temperature envelope and should not be read automatically as a particular chromium-molybdenum family. Its distinction from carbon-steel or stainless-steel pipe must come from the specified material chemistry and product requirements. Selection depends on the approved grade, manufacturing route, heat treatment, weldability, medium, design conditions, examination, and traceability required by the project.
