Stainless Steel Bright Bar

We offer bright stainless steel bars which are appreciate to dimensional accuracy, and high tensile strength. It's outstanding in hospital, machining components, hardware, kitchen and so on.

Process: We produce bright bars by using following process.

Annealed, pickled, cold drawn, centreless ground & polished.

Peeled, straightened, centreless ground & polished.

Different kinds of stainless steel

Type Precipitation hardening stainless Martensitic stainless Duplex & super duplex stainless Austenitic stainless High alloyed austenitic stainless

Character Corrosion resistance, hard High carbon content, magnetic, low ductile Resistance to stress corrosion and crevice corrosion Content: chromium 18% and nickel 8% Non magnetic and no heat treating Content: chromium, nickel, molybdenum and nitrogen. Superior resistance to corrosion and higher strength

It's full of stainless steel bar in the warehouse with bright surface and exact dimension.

Stainless steel bars can be cut into different sizes according to your requirement. It's good material of ball bearing, pump shafts, and valves.A bundle of stainless steel bright bars is packed and prepare to be hung to the warehouse.

The whole bundle of stainless steel bright bar can be packed with inside a layer of plastic film, outside woven bags and tied by iron straps.

An instrument used for testing the content of component.

We have special instrument to test the content of component of the stainless steel bright bar.5 pieces of stainless steel bright bar in a row, each row is separated with wood stick.

Stainless steel bright bar with corrosion resistance is used in oil/liquid cargo ships.

Advantage

Dimensional accuracy. With the process of strengthening, grinding and fault detecting, stainless steel bright bar is more accurate with straightness max. 0.5 mm/m and roughness max. 0.4 um.

High strength. During the process of annealed, the temperature increasing slowly, the molecular structure is much closer and high tensile strength is also improved.

Corrosion resistance. Chromium and nickel are adopted in the austenitic steel, which increase capability of corrosion resistance.

Excellent work-hardening.

Application

With the advantage of accuracy dimension, high tensile strength, hardness and corrosion resistance, stainless steel bright bars are widely used in diverse areas:

Machined components, valves, machine tools, pump, shafts, fasteners, dairy equipment, surgical & medical parts, threaded bars, studs, bolts, ball bearing and races, nozzles.

Hardware application & kitchen application and so on.
