Product Description
18Cr2Ni4WA Alloy Steel Round Bar 180mm OD
18Cr2Ni4WA (18Cr2Ni4W) is a high-strength, high-toughness carburizing alloy structural steel manufactured to GB/T 3077. After carburizing and quenching-tempering, it delivers excellent core strength, surface hardness and fatigue resistance, making it an ideal material for heavy-duty gears, shafts and high-load transmission components.
