Relevance
Difficult operating conditions in modern industry require a wide application of heat-resistant steels based on the alloy chromium-Nickel alloys such as KHN60VT. Production, mechanical and physical properties of the tape KHN60VT (sometimes this alloy indicate ВЖ98, ЭИ868, KHN60VT-sh or KHN60VT-VD) reglamentary GOST 5632−72.

Production
The alloy is melted by means of open electric furnaces with the use of the technology of plasma-arc remelting and has the following options: KHN60VT-P, KHN60VT-sh, KHN60VT-VD and others. Accordingly, in the technical literature of other countries can meet the following symbols ЭИ868-P, ЭИ868-sh, ЭИ868-VD, etc. According to the normative-technical documentation, tape KHN60VT manufactured according to TU 14−1-927−74. Tape thickness varies from 0.3 до0,5 mm, and a width of 100 mm.
Treatment
Like all heat-resistant alloy steels, alloy KHN60VT poorly machined. The cutting material must be used dvuhserijnyj plates from hard alloys (group TTC). As a cutting fluid recommended UNIZOR-80. But the tape has good weldability and does not require preheating and subsequent heat treatment. Details for the manufacture of which used cold-rolled strip KHN60VT subjected to hardening at a temperature of from 1150 to 1200ºC cooled under a water shower or air. The procedure of heat treatment time intervals and temperatures are regulated ST CKBA 016−2005. Limit short-term strength of such a strip does not exceed 980 MPa, and relative elongation at break less than 30%. With increasing temperature both are reduced. If the temperature in which the working parts of this alloy reaches 1100ºС, it starts the process of intensive formation of scale.
