Production

All around is a metal bar having a circular cross section. Round KHN70JU, tend to produce a length of 2−6 m. the Precision manufacturing it is marked with the letters A, B, C, which means high precision, improved accuracy and precision of conventional production. According to the method of heat treatment range is thermally treated — T, without heat treatment, and N — full hard (repeatedly subjected to rolling). Length of wire, rod, circle is dimensional, random length and length is a multiple dimensional. Recommended temperature of quenching of the alloy in air or in water not higher than 1200 °C. the Temperature of raskopki began at the beginning of 1150 — 1180 °C, and in the end 850 °C. This alloy is easily weldable any type. For manual electric arc welding used electrodes OzL-35, OzL-25.

Application

Wire, round and rod KHN70JU used in the production of conveyor furnace nets, parts slot furnaces for fast firing ceramic tiles and other ceramic products. The details of this alloy can operate reliably in hazardous conditions and corrosive environments at a temperature of 1250−1300°C for a long time, has a high resistance at high temperatures to the load. Also, this steel is used in the form of blanks for the production area, beams, channels and special purpose profile for industrial construction of any complexity. Round KHN70JU actively used in mechanical engineering. It is used as a workpiece for the production of axles, bushings, pushers, shafts, etc. moving parts. The wire is used for different fasteners and welding electrodes.
