Product brief introduction

This type of steel is mainly used in the production of medium- and medium-loaded parts in the tempered state, or used as a high-load and low-impact part in the quenched and tempered state. It can also be used as a large section and requires surface hardening. Parts. In the general machinery industry, this steel is used to make transmission gears, spindles, spindles, shafts, connecting rods, worms, electric axles, generator shafts, crankshafts, flywheels, and forgings; in steam turbine manufacturing
