20MnCr5 Gear Steel Bar
Solid Round Bar Products Description
20MnCr5 round metal rod is an alloy carburizing steel with high strength and toughness, good NMenability, and better performance than 20Cr after heat treatment.
20MnCr5 solid steel round bar is used to manufacture large-section and heavy-load quenched and tempered parts and small-section carburized parts.
At the same time, 20MnCr5 solid round bar steel can also be used to manufacture small and medium-sized parts with medium load and small impact, such as gears, shafts, spindles, friction wheels, worms, speed regulator sleeves, etc. of speed change equipment.
