The valve stem is not only a moving part, a force receiving part but also a sealing part during the opening and closing process of the valve. At the same time, it is subject to the impact and corrosion of the media and also creates friction with the filler. Therefore, when selecting the valve stem material, it must be ensured that it has sufficient strength, good impact toughness, scratch resistance and corrosion resistance at the specified temperature. The valve stem is a wearing part, and the mechanical processing property and heat treatment performance of the material should also be paid attention to when selecting.
