TZM molybdenum plug for piercing steel rods
The molybdenum ( TZM ) piercing mandrel is a critical component used for piercing seamless tubes of stainless, alloy steel and high-temperature alloy, etc. It is typically made of a molybdenum alloy (TZM alloy), which has excellent high-temperature strength and oxidation resistance. The high-temperature stability and corrosion resistance of molybdenum (TZM) piercing mandrels make them an essential component in the making seamless tubes process.
