30CrMoDie Steel

1.Product Overview

30CrMo, also known as chromium-molybdenum alloy steel, is a medium-carbon quenched and tempered steel with high strength and toughness. This steel exhibits good high-temperature strength below 500°C, along with excellent hardenability, temper stability, and corrosion resistance. 30CrMo is widely used in manufacturing parts requiring high strength and wear resistance, such as automotive engine crankshafts, planetary gears, and drive shafts. It is also used in industrial equipment like high-pressure vessels, boilers, and petroleum machinery.
