Company Overview Bright Annealed Stainless Steel tubes B.A(Bright annealed) stainless steel tubes are mainly used for super clean gas pipe line. And surface roughness, dimension tolerance and mechanical properties are controlled by cold drawing process. With high corrosive resistant properties ILJIN clean B.A tubes are manufactured by special process. Application Toxic and high purity gas supply line for semi-conductor and LCD manufacturing Instrument tube for oil & gas Painting & Sanitary use( beverage, drink, Medical) Damper & Gas spring Power plant Heat exchanger and Boiler Automobile parts ( Engine fuel rail, Exhaustion system) Precision Roller Shaft fitting History (Stainless Steel) 1982. 05.
