Electropolished Stainless Steel Tubing is especially done on 300 and 400 series stainless steel that improves a part's corrosion resistance which leaves a lasting bright finish. Unlike passivation electropolishing can be performed on all varieties of stainless steel which gives its parts of all kinds corrosion resistance superiorto passivation alone—electropolished parts are 30 times more corrosion resistant than those that are passivated. The process of dissolving a uniform layer of surface metal is more effective and aggressive, because it is highly controlled and it can be used to remove as little as .02″ of surface material.
EP Pipes are widely used by surgeons and dentists, appliance manufacturers, automakers and the racing industry and in food, beverages and pharmaceutical processing. SS 304 Electropolished Pipes has an excellent forming and welding characteristics. It is excellent in a wide range of atmospheric environments and many corrosive media. In warm chloride environments it is subject to crevice corrosion & pitting.
All Chhajed products are manufactured under strict process control and monitored throughout the production process. They go through several checks to ensure that the product delivered is of finest quality!
