Round steel with a bright surface and no rolling defects and decarburization layer on the surface. It can be subdivided into peeled, polished, and polished materials. Silver bright steel is used as machine structural steel for various specialized purposes, such as for bolts with strong wear. In addition, such as spindles, piston rods, spokes, and similar components can be used as tool steel in the quenched state.
High weldability and cold strain plasticity, with a certain strength, hardness. Good plasticity and toughness. Medium machinability, poor hardenability and hardenability. Good strength and toughness after quenching and tempering at low temperature. No tempering brittleness tendency. Generally used for manufacturing heavy and medium machinery in the load of cold stamping parts, small forgings and machining small parts such as washers, pins, bolts, nuts, etc.; After carburizing or carburitriding, friction plates, piston pins and unimportant gears can be made; After normalizing treatment, can be used as -20 ~ 475 ºC pressure vessel forging steel. Welding parts, hot forging, hot stamping parts after carburizing used as wear-resistant parts.
