Shu workers: 18121031197, phone: 021-58337982, QQ: 1749526762 age hardening: aging hardening, usually after rapid cooling or cold. Aging: metallurgical characteristics change occurs slowly at room temperature (natural aging) and metallurgical properties of the rapid changes occurring at high temperatures (artificial aging). Annealing: In order to reduce the hardness, improved processing properties or to obtain the desired mechanical properties such purposes, a specific material is heated and maintained at a suitable temperature and then cooling at an appropriate rate (see also the thermal processing answers). Austenitic: iron-based alloy face-centered crystal phase. Austenitic steel: at room temperature microstructure composed mainly of austenite steel. Austenitizing: the iron metal is heated to a temperature within the range of conversion to form austenite (Part Austenite) or iron metal is heated to a temperature exceeding the conversion range to form austenite (fully austenitic ). Since the stress process: applying and releasing the internal components in thick build residual compressive stress of technology through the internal pressure, making the inner diameter of the hole near the metal element or compressibility. Lubricator (BOP): can pressure of machinery and equipment, used in drilling fluids and drilling fluids to control wells. Brazing: low melting filler metal thin layer of non-ferrous metal flows into the gap between the metal connecting metal.
