Evaluation of Nickel-Base HYBRID-BC1 Alloy Explosion Clad

Explosion clad test plates of hybrid alloy N10362 clad to carbon steel, ASME/ASTM10 SA51615 Grade 70, were manufactured and evaluation for corrosion resistance.  Bond ultrasonic properties, metallographic bond visual quality and a set of eight criteria.

Nickel-base HYBRID BC1 Alloy offers superior corrosion performance to established Ni-Mo and Ni-Cr-Mo alloys in several specific severe corrosive environments. Explosion cladding of BC1 to a lower cost base metal provides significant cost reduction for pressure vessels and other process equipment requiring heavier thicknesses (typically 12mm (0.5 in) and greater). Alloy BC1 explosion clad plate with SA-516-70 base metal was extensively evaluated for compliance with clad metal specifications corrosion resistance thermal stability and ability to be formed fabricated and heat treated for ASME Code pressure vessels. The corrosion resistance properties of the BC1 cladding layer were unchanged from typical solution annealed properties after the sequence of explosion cladding head forming and post weld heat treating. Bond shear strength and product ductility of the clad plate were compliant with the requirements of SA-265. Ultrasonic inspection showed no recordable indications of the test plate which simulated production of plates up to 4800 x 6100 mm (188 x 240 in).
