Project Description

6J15

6J15 is a non-magnetic material with high corrosion and oxidation resistance. Fine resistance to aqueous corrosion as it significantly prevents deformation when kept in contact of liquid solutions, and provides longer service life. It has the highest service temperature up to 1150℃.
