Technological processing

The circles are made by hot method of typical diameter of 5 to 270 mm, but under the order of the dimensions may be others. Ready-prepared foods are subject to ruskovce from the initial temperature of 1170 °C to t° 850 °C. Steel is cooled after the deformation in the open air, in water or in oil. There is another way, involving cooling with water, followed by aging products for 4−5 hours.


In high temperature installations at temperatures over 1000 °C. the Content of cobalt and chromium alloy provides high resistance to gas corrosion. This steel is indispensable in manufacturing the most important high-temperature parts.
