Stainless Steel Bushings and Sleeves for Heat Treatment Furnace and Galvanizing Line

As for the ternary ceramic cobalt-tungsten alloy, 2B bushing, bushing and sleeve developed by our company, their superior wear resistance, corrosion resistance and crack resistance are 5-6 times better than the similar product. (sink roller sleeve and arm sleeve can be used continuously for about 30 days, stable roller sleeve and arm sleeve can be used continuously for about 60 days)

The new material IB developed by our company overcomes the defects of sinking roller and stabilizing roller, such as short service life, slime on the surface of shaft body, serious corrosion, low hardness and changeability. The mechanical property of IB new material is 4-5 times better than 316L material and the wear resistance is 3-4 times better than 316L material.

IB material is a novel product produced by combining with the actual application of our company and research institute. It belongs to the basic material of our company's internal control ultra-low carbon Ni-Cr-Mo-Co alloy. We add other alloying elements which will help to purify the grain boundary and not to react with zinc liquid. IB material has the very good liquid zinc corrosion resistance, better toughness and wear resistance of composite effect. IB material has the economic effect of practical use in the galvanizing industry.
