Union fittings are typically made from materials like stainless steel, brass, carbon steel, and copper alloys, all selected for their strength and resistance to corrosion. Stainless steel grades such as 304 and 316 are especially prized for their ability to withstand high pressure and temperature. These fittings boast excellent tensile strength, hardness, and ductility, ensuring tight, leak-free connections even in challenging environments. Their mechanical properties—like high fatigue resistance, good weldability, and durability—make them ideal for hydraulic, pneumatic, and process piping systems where reliability and safety are paramount.
