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

ZF Marine Krimpen applied Subsea Industries' Ecoshield reinforced coatings (purchased from the product library) for its azimuth thrusters (purchasing supplies) nozzles and underwater parts for inland waterway operations.
     The Dutch-based ZF Marine Krimpen is a division of the German ZF Group. Currently, ZF Marine Krimpen is using Ecoshield coatings on propellers for several US customers to reduce wear and tear in brown water such as the Mississippi River.
     ZF Marine hopes to improve the protection of the underwater part of the propeller and to prevent damage caused by cavitation corrosion caused by intrinsic waterways, especially the common waste, sand and silt of the Mississippi River.
     ZF Marine offers a choice of Ecoshield propellers as an option to demonstrate that the coating is a very good solution for prolonging the life of the tugboat (ship type shipyard) and pusher (ship type shipyard) propeller life in shallow water. . The coating not only does not cause propeller damage, but also reduces maintenance and operating costs. These advantages are not only reflected in the tugboat, but also in port tugs and passenger ships (ship-type shipyards).
