Methods of production and use of stainless steel
Austenitic steel
70% of today’s stainless steel has stainless austenitic steel. They contain 16% chromium and 6% Nickel. Can be added elements such as titanium, molybdenum or copper. They are added to the alloy in order to improve heat resistance, heat resistance, corrosion resistance. Production cost of austenitic alloys is relatively high, It has broad applications

Doping helps to increase the performance, allows the production of ferritic steels the most important parts.
Duplex steel
It got its name because it includes ferritic and austenitic microstructure, therefore, has the properties of austenitic and ferritic stainless steels. Duplex typically contains 2.5−4% molybdenum, chromium 18−28% and the Nickel content reaches 4.5−8%.
Application
Details gas and steam turbines of stationary power and boiler plants, parts of household appliances, pumping petroleum products, natural gas, hydrogenation of the fuel.
