Nickel is a metal structural material that is resistant to high temperatures, high pressures, and can be used in a variety of harsh corrosive environments in the chemical, petroleum, non-ferrous metallurgy, aerospace and atomic industries.

Nickel clad stainless steel plate is a new type of metal structural material that is composed of the chemical properties of nickel and stainless steel. In equipment made of this composite material, the nickel layer prevents corrosion of one medium and the stainless steel layer prevents corrosion of another medium. The nickel clad stainless steel plate thus designed is naturally more novel and superior than the above many composite sheets. The nickel clad stainless steel plates we produced were obtained by explosive welding and subsequent rolling.

The method of adding a little high explosive explosive under the detonator can reduce the detonator area and enlarge the joint area ratio. The results of the detonation direction and the center line of the composite board indicate that there are waveforms in the entire joint zone. Moreover, as the detonation wave propagates, the waveform has a development process: there is a linear combination section at and near the detonation position, followed by a small waveform, and then gradually increases. After 140 mm, the waveform size and waveform shape tend to be stable.
Shape deformation and regularity of the metal in the waveform of the composite zone of other composite materials can also be observed in one waveform. There are two vortex zones in the waveform, the pooling zone of the dissolved metal. The element content distribution test of the combined zone shows that there is an interdiffusion zone of dissimilar metal atoms near the interface. Nickel and stainless steel are metallurgically bonded in these metallurgical processes.
