General characteristics

Chrome margantsevokisly alloy 20KH20N14S2 (ЭИ211) austenitic class belongs to the category of high alloy high-temperature steels. In addition to chromium, iron and manganese, forming its basis, the structure includes a number of additional alloying elements: silicon, titanium, copper, which greatly increase the original quality of the material and ensure stability of its performance.


The most important qualities steel grade 20KH20N14S2 include ductility, high temperature strength and corrosion resistance. These qualities allow a wide use of semi-finished products made from similar raw materials in modern industry at high temperatures. Thanks to the optimal technological and operational parameters such material actively resists corrosion, withstands repeated thermal shocks.
