The inter-crystal corrosive test is a common local corrosive of metal corrosive, which begins on the surface of the metal and moves along the crystal line to the inside of the crystal particle, reducing the corrosive strength of the crystal and reducing the strength of the material, which in serious cases is completely lost to its mechanical strength, and is one of the highly hazardous forms of local corrosiveness.

The equipment is designed to test inter-crystal corrosive conditions of different materials at different temperatures by incorporating corrosive reagents, intercrystal corrosive, one of the local corrosives.Metal crystalThe sub-interface between them extends to the internal corrosiveness. The main reason is the difference in the chemical composition of the crystal surface and the internal cortex and the presence of the crystal impurities or internal stress.Metals are brightThere's no sign of destruction, but the confluence of the crystals is weakened, the mechanics are deteriorating, and they can't withstand a knock, so it's a dangerous corrosion.stainless steel.In nickel-based alloy. The corrosive crystals of stainless steel welding are a major problem in the chemical industry.

The method of testing inter-clinic corrosive of metal materials under specific media conditions and the sensitive accelerated metallic corrosive test method is designed to understand the soundness of the chemical composition, thermal process and process of the material. The rationale is to use various test solutions that can place the corrosive power of the metal at a specific area of the helionic arctic polar curve, using the difference between the crystal particles of the metal and the crystal boundary to accelerate intercorrosion of the current.
