Composition and properties
The group of these steels includes several brands of high-alloy medium carbon steel. The carbon content in the range of 0,2…0,4%. Common to these materials is the high content of chromium, molybdenum and vanadium, some steels contain tungsten, titanium and boron. In steels not permitted the presence of fixed nitrogen, while minimizing non-metallic inclusions is achieved by a high content of aluminum used for deoxidation full.
Relaxation-resistant steel produced by the enterprises, but some of them are on the list of alloy steels, smelting which is done in accordance with technical requirements GOST 4543.
For the mechanical and metallographic properties of heat-resistant relaxation resistant steel characterized by:
