stainless steel rod knowledge

Stainless steel bars include stainless steel black bars, stainless steel bright bars, stainless steel round bars, stainless steel square bars, stainless steel hexagonal bars, stainless steel special-shaped bars, stainless steel free-cutting bars, etc.

The surface of the stainless steel bright rod is bright, that is, the hot-rolled stainless steel black rod is cold-drawn through a cold rolling mill to remove the black color on the surface. Stainless steel bright rods are generally cold drawn, finely ground, or polished, with good surface brightness and wide applications.

Stainless steel black bar is our customary name. The proper term is stainless steel hot-rolled bar, which is a stainless steel bar that is hot-rolled. Since the stainless steel bar comes out of the hot rolling furnace, the temperature will be very high, and the surface will be black when it is naturally cooled

Difference between the flat bar and steel plate

The main difference for both of flat bar and steel plate is about technology craft. The flat bar steel belongs to structural steel such as angle bar and steel channel, etc. with molding method of hot rolled and cold drawn. lts hot rolled flat bar is width with max 150mm, and thickness with max 60mm. However flat bar's edge is a circular arc..
The flat bar steel is widely used. It looks like a slab cut from a common steel plate, but it is actually hot rolled. The edge of flat steel is called olling edge. Rolling edge guarantees the strength of its edge.
