Technological properties

Name The value
Particularities of production of goods Sheets hot rolled sheets and steel cold-rolled strip supplied on the other 14-1-3021-80 without heat treatment. The value of the frequency temperature coefficient (BPC) of all sizes after heat treatment under the regime of a supplier should not exceed ±30·10-6 deg.-1 in the temperature range of +20÷100 °C and ±40·10-6 deg.-1 in the temperature range -60÷+20 °C. the quality Factor of the alloy should be not more than 1500. BPC and the quality are checked according to the methods attached to THAT 14-1-3021-80, samples 10h120 mm or 8х50 mm cut in the longitudinal direction of the finished strips and sheets after the heat treatment regime: Heating in a vacuum at a temperature of 950-1050 °C for 1-2 hours, cooling the container air.
Storage Products THAT 14-1-3021-80 should be stored in a dry place at a temperature of from 1 °C to 40 °C.
