20CrMnTi isCarbonized steelCarbonized steel is typically low-carbon steel with a carbon content of 0.17%-0.24%, often used in the automotive industry for manufacturing drivetrain components.GearIt is a Cr-Mn-Ti alloyed through-hardening carbon steel with high through-hardening properties. It maintains high low-temperature impact toughness while ensuring thorough hardening. The 20CrMnTi steel is used for surface carburizing and hardening treatments. It exhibits excellent machinability with minimal deformation and superior fatigue resistance. Main applications include shafts, piston components, and various special parts for automobiles and aircraft.

High-performance carburizing steel with good hardenability, featuring a hard and wear-resistant surface and a tough core after carburizing and quenching. It boasts high low-temperature impact toughness, moderate weldability, and good machinability after normalizing. Suitable for manufacturing critical components that withstand high-speed, medium, or heavy loads, impacts, and friction, such as gears, ring gears, gear shaft crossheads, etc., with cross-sectional dimensions less than 30mm. It is a substitute for 18CrMnTi steel, widely used for carburizing parts in the automotive and tractor industries. These parts, with cross-sectional dimensions under 30mm, are subjected to high-speed, medium, or heavy loads and impacts or friction, including gears, shafts, ring gears, gear shafts, main shafts of sliding bearings, crossheads, claw-type clutches, worm gears, etc.
