Product Description

About products

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.
