304L stainless steel bar: As a low carbon 304 steel, in general, corrosion resistance is similar to 304, but after welding or stress relief, its grain boundary corrosion resistance is excellent, in the case of no heat treatment, also can maintain good corrosion resistance. Stainless steel round steel belongs to a class of long wood, also belongs to a class of bar, the so-called stainless steel round steel refers to the cross section of uniform circular long wood, generally about four meters long. It can be divided into light circles and black rods. The so-called light circle, refers to the smooth surface, after the quasi-rolling treatment; And the so-called black rod, refers to the surface of the black thick, hot rolled directly. Stainless steel round steel can be divided into hot rolling, forging and cold drawing according to the production process. Hot rolled stainless steel round steel is 5.5-250 mm in size. Among them :5.5-25 mm small stainless steel round steel mostly to…
