Precision piston rods are widely used connecting components, applicable in virtually all mechanical products. Common materials for these rods include 45 steel, 40Cr, 2Cr13, and others, which require specific processing procedures, such as electroplating and heat treatment, to achieve specific properties and meet certain requirements. Therefore, they must undergo heat treatment to obtain excellent strength, surface hardness, and resistance to corrosion, friction, and galling. Heat treatment methods for precision piston rod materials include:
1. 45# steel
Heat Treatment Process: Preliminary Heat Treatment - Low Temperature Spheroidizing Annealing - Quenching - Critical Temperature Quenching - High Frequency Quenching
2、40Cr
Heat Treatment Process: Preparing heat treatment - Eliminate internal stress of the workpiece - Quenching and tempering operations - Quality inspection of the workpiece
3、2Cr13
Heat Treatment Process: Preparing Heat Treatment - Tempering - Stress Relieving - High-frequency Quenching, Low-temperature Annealing
