Alloy Pipe and Tube

American Piping Products stocks a range of 4100 series alloy products used by original equipment manufacturers (OEM) and in oil and gas applications. The 4100 series uses Chrome and Molybdenum to increase the strength and wear characteristics of carbon steel. American Piping Products has a long history with Chrome/Moly steels for the power industry, so the 4100 series is a natural addition to our current inventories.
