1. product Introduction
GR2 titanium clad steel plate began in 1962. At that time, the production method was called the "explosive clad method", which was a method of bonding by virtue of the explosive energy of explosives. The hot rolling method and thick plate rolling method were developed in 1986. In 1990, the production method of the continuously hot-rolled coil was developed, mainly referring to the production of thin plates. Titanium has high strength, and the maximum tensile strength of pure titanium can reach 180kg / mm2. Titanium is widely used as various chemical reaction vessels and heat exchangers because of its excellent corrosion resistance, but the disadvantage is that the cost is high. The composite of Gr2 titanium and ordinary steel is called GR2 titanium clad steel plate. It has both the corrosion resistance of titanium and the strength of ordinary steel plate as a structure. The important thing is that the cost has also been greatly reduced.
