      1- Traction machine with capacity of 40 tons<\/strong>
      This machine is made by the German company Zwick and is used to perform tensile testing for raw materials and welded parts. By replacing its jaws, both parts up to 12 mm thick and round parts up to 25 mm in diameter can be tested. This device has an extensometer. It is connected to the device, which can also measure the amount of increase in length, and with the software that is on its system, shows the amount of force applied instantaneously, and at the end, draws the corresponding stress-strain graph that shows the final yield point and strength. The piece is marked on the chart<\/p>

      2- Traction machine with capacity of 100 tons<\/strong>
      This device is also made by the German company Zwick, which is unique in terms of accuracy and amount of applied force in the country, and in addition to having the features of the above device, it has the ability to test parts up to 120 mm thick.<\/p>

      3- Impact device with a capacity of 300 joules<\/strong>
      This impact test machine with a capacity of 300 joules is made by Centam Co. Impact test specimens are prepared by the prototyping workshop and the length, groove depth and angle of the specimens are controlled by a light microscope. The hammer of this device operates electrically and is updated in its kind. The impact test temperature is controlled by a digital thermometer capable of displaying up to -196 \u00b0C<\/p>

      4- Hardness testing machine<\/strong>
      The mechanics laboratory has two Swiss hardness testers and a Russian hardness tester. A variety of hardness scales including Brinell hardness, Rockwell method and Vickers method can be measured with these devices, all of which have block test devices. Test blocks have a certificate from the manufacturer or other companies, and before starting, these devices.<\/p>

      5- Micro hardness equipment<\/strong>
      The micro hardness device is made by the German company BUEHLER and has the ability to measure the hardness of phases and coatings with a load value from 10 to 1000 grams. With this device, it is possible to report hardness based on Vickers and Knopp method for different phases and coatings in the metallurgical laboratory.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

      8- Quantometric analysis devices<\/strong>
      These devices are made by ARL America (with the new name of Thermo), which are capable of chemical analysis with very high accuracy and speed, and are able to determine the analysis of steels in less than one minute. These devices are capable of measuring 21 elements including carbon, silica, sulfur, phosphorus, manganese, nickel, chromium, molybdenum, copper, aluminum, vanadium, titanium, niobium and …. The basis of analysis of these devices is iron. There are currently two quantum analyzers in the Central Laboratory, one capable of analyzing 17 elements and the other 21 elements.
      Calibration and service of these devices are performed periodically and regularly by specialized companies and are calibrated daily based on international standard samples for analysis.<\/p>

      9- Stroline gas measuring devices<\/strong><\/p>

      These devices are made by the German company Stroline. MSA is one of the few companies with gas measuring devices. In this laboratory, there are 2 samples of these devices that are able to measure the amount of hydrogen, oxygen and nitrogen of the melting samples with ppm accuracy. One of the experiments that has been used continuously during the past years is measuring the amount of bandage melting gases, which has been required in preparing train wheels for the Railway Company of the Islamic Republic of Iran according to the standard.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
