Throughout the manufacturing and distribution supply chain common terminology is used. The terminology is not exclusive to titanium however is important to define and understand.
Plate – Flat rolled mill product that is normally hot finished, more than 200mm wide and 3.175mm thick.
Sheet / Strip – Have thickness between 0.635mm and 3.175mm and produced as a coil with sheets being cut to required length.
Bar – Used as references to squares, rounds, hexagons and profile shapes with cross-sections above measuring at least 9.525 in cross-section.
Wire Rod – Semi-finished wire product made for the production of wire.
Wire – Typically wire produced from cold drawing a wire rod.
Foil – Has thickness less than 0.127mm and of any width.
Tube Product – Used to describe hollow titanium product which are normally a cylinder shape like those used in heat exchanger tubes.
Ingots – Are the largest form of titanium product in a cylinder form with a 1.5 length to diameter dimension ratio. The ingot are typically 86cm in diameter and 248cm long and are approximately 6tonnes
Blooms – This refers to a semi finished product either billet, slab or bar which has been formed by hammering or rolling a titanium ingot.
Billets – These are semi-finished products with a square section of titanium produced by rolling either a bloom (as above) or titanium ingot
Slabs – Semi-finished product with a rectangle cross section and where the width is double the thickness at least.
Heat Treatment – Heat treatment is the process by which the properties of metals are changed by applying heat cycles to the metal. How long the heat is maintained for certain temperature values along with the cooling cycle rate is as important as the temperature. The reason why heat treatment is performed is to change the material properties so as to make it more machine-able, increase toughness, enhance cold forming, improve ability to shear, change tensile properties and stress relive.
Annealing – Refers to the processes which involves adding heat and slow cool cycles to change toughness and ductility. The annealing process makes the titanium softer and so easily formed, machined and sheared.
Stress Relief – The action of removing “residual stress” from a metal
Quenching - Fast cooling of a metal from a high temperature usually through application of a coolant.
Grinding, Turning, Polishing – The machining processes which are typically applied to bars to enhance surface quality and precision.
