20CrMnMo hot rolled steel round bars

Product introduction

Good thermal processing performance, normalizing after a good cutting performance, after quenching and tempering with good mechanical properties and low temperature impact toughness, after carburizing have high flexural strength and wear resistance, but poor weldability, to properly warmed up before welding, after welding should be tempered. Commonly used in the manufacturing requirements of high surface hardness, good wear resistance is important carburizing parts, such as gears, camshafts rod,
