17Mn4 steel pipe is used for the high-temperature constructional, weldable steel for forgings and tubes of constructions for steam boilers, pipelines, pressure vessels and plant manufacture. We supply the 17Mn4 steel pipe with high quality and different s

The SA335 P9 alloy steel seamless pipe is a carbon steel pipe, and chromium and molybdenum are subsequently added. Sometimes vanadium is called a chromium-molybdenum pipe. SA335 P9 alloy steel seamless pipe is used for high temperature applications accord

The use of seamless steel tubes has become widespread. Seamless steel tubes are a type of pipeline that is resistant to weak acids such as air and steam. However, it will be corroded in a strong alkali and strong acid environment. Some measures should be
