PRODUCT DETAILS
Product introduction
steel round bars are widely used in machinery making, autombile making, railway, mine machinery, petoleum machinry, agricultural machinery and civil archtectue such as all kinds of shafts, screws, connecting rods, hardware tools, gears, standard parts, spanners fasteners, structural parts for automobile and agricultural machinery, outer and iner sleeves, rollers and balls for bearing making.
GB 20CrMo steel is a kind of Chinese alloy steel for engineering and mechanical structure purpose, which is generally used in quenching or tempering or carburizing and quenching. 20CrMo material has high heat strength, good hardenability, no temper brittleness, cold strain plasticity, good machinability and weldability.
