BRIGHT STEEL BAR
Bright steel bar is carbon or alloy steel bar with shining bright surface which is improved by cold drawing, peeling, turning, grinding and polishing over hot rolled black surface bars. By cold drawing, the steel bar yield strength and tensile strength will be improved. By peeling and turning, the surface imperfections will be removed. By grinding, the diameter tolerance will be more precision. By polishing, the surface will be much more shining.
Except the shining bright surface, comparing with the hot rolled black surface bars, the bright steel bars has better surface roughness, better roundness, straightness, more precision size tolerance etc.
Heat treatment such as annealing, normalizing, quenching and tempering will be done before do cold finishing on the hot rolled bar to get bright steel bar, in such condition, the steel bright bar will get most suitable mechanical properties to meet different application requirement.
The advantages of steel bright bars we supply:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Heat treating furnaces to adjust the mechanical properties
3) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
4) Multiple packages to avoid broken packages and anti-rusty
