The stainless steel pipes and tubes of 430 ERW are ferritic type that contain from 16 to 18 percent chromium. Grade 430 or UNS S43000, or EN 1.4016 has magnetic properties, good oxidation and corrosion resistance and also does not have any intentional addition of nickel in order to keep the price less than the 300 series. These tubes are used for automotive trim, kitchen equipment, appliances, architectural parts and industrial heating equipment. Amardeep Steel Centre supplies them in India for domestic and export orders. Compare our SS 430 tubes and browse SS welded pipes and tubes.
