Those x s technologically properties of metals and Silava - properties indicating suitability level of metals and alloys for processing, forging, binding and cutting and RCT
Fluid flowability - properties of metals and alloys, which is contributing to shaping so filling in their liquid state
Ductility - the property of metals and alloys, which contributes to the change of shape without destruction during forging, stamping and rolling
The property of welding - The property of metals and alloys, which contributes to the formation of a strong and dense compound
Treatment Res aniem - quantity, estimated chips at weight ohm obtosyvanii e dyanitse in time or at a certain p and m are working time.
Perlite is a eutectic mixture of ferrite and cementite.
Ledeburite is an eutectic mixture of austenite and cementite, formed at a temperature below 1145 ⁰ C
Graphite - mineral hex on th onal polymorphic modification of carbon, is in the form of plates or a face catch
Carbon instrument-making steels are non-machined structural and tool steels containing carbon (0.04-2 % ).
Alloyed steel - in addition to the usual impurities, contains alloying elements to impart certain physical, chemical or mechanical properties to the alloys, in which there is chromium , nickel, molybdenum, tungsten , vanadium and a friend.
Stainless steel - steel, resistant to electrochemical corrosion, is obtained by adding alloying elements to the composition of carbon steel
Refractory steels - steel, which does not collapse under the influence of high (above 550 ⁰ C) temperature and gases
Heat resistant steels - Steel, which is used for the manufacture of parts, under load at high temperatures.
Heat treatment - a set of operations thermal effects on metals and a set of operations thermal effects on metals and alloys for the purpose and edited neniya structure and with properties in the desired direction, by annealing, hardening, tempering, normalization and others.
Steel softening - the process in which steel is heated to a certain temperature, this temperature is held for a certain time, after which it is slowly cooled
