These plates are alloyed with chromium, molybdenum, and other elements for superior strength and wear resistance. Heat-treated (quenched and tempered) to meet specific mechanical properties, they are used in crankshafts, gears, and pressure vessels. Compliant with GB/T 3077 and ASTM A285 standards, our plates undergo ultrasonic testing and chemical analysis for quality assurance. Custom machining services (milling, drilling) available.
