J & J Alloys is and industry leading manufacturer of nickel alloy fitting and flanges with a wide array of standard as well as specialty products we are capable of producing.
These stainless alloys are austenitic chromium steels containing columbium. The addition of columbium produces a stabilized type of stainless that eliminates carbide precipitation, and consequently, intergranular corrosion. They are recommended for parts fabricated by welding, that cannot be subsequently annealed. They also are used for parts,that can be intermittently heated and cooled to temperatures between 800° and 1600° F.
