Annealing (metallurgy) brass can be cooled slowly in air, or quickly by quenching in water, unlike ferrous metals, such as steel, which must be cooled slowly to anneal. In this fashion, the metal is softened and prepared for further work—such as shaping, stamping, or forming. Annealing occurs by the diffusion of atoms within a solid material, so that the material progresses towards its equilibrium state. Heat increases the rate of diffusion by providing the energy needed to break bonds. The movement of atoms has the effect of redistributing and eradicating the dislocations in metals and (to a lesser extent) in ceramics. This
Metal hose areas of application: Metal hoses resist high pressures and offer maximum tightness on account of the material from which they are manufactured. Their flexibility lends them tensile and tear strength. Also, they are characterised by their corrosion and pressure resistance, even under extreme conditions such as when exposed to aggressive seawater, strong vibrations and extreme temperatures such as in space or when transporting cooled liquid gas. To increase pressure resistance, metal hoses can be equipped with one- or two-layer braiding. The braiding is firmly connected to the hose fittings on both sides to absorb the longitudinal forces caused by internal
