This product is a high-pressure cylinder casting for steam turbines, manufactured from ZG15Cr2Mo1 heat-resistant alloy cast steel with a single-piece weight of 41 tons (customization available). The product undergoes normalizing and tempering treatment, delivering outstanding high-temperature strength, creep resistance, and microstructural stability. Throughout the process, precise temperature control is achieved using contact thermocouples, ensuring stable heat treatment, optimizing grain structure, eliminating casting stresses, and guaranteeing product stability and reliability under high-temperature, high-pressure operating conditions. Product quality strictly adheres to GB/T9444-2007 standards through magnetic particle testing (MT), meeting Grade 2 requirements. Ultrasonic testing (UT) is performed on thick and large sections. Self-inspection results indicate uniformly refined grains without coarse grain phenomena, ensuring dense, uniform internal quality without defects and meeting Grade 2 standards. As critical pressure-bearing components for steam turbines, these parts provide core assurance for stable unit operation.
