CrN55VMTKU (circle, wire, tube, sheet, strip) (ei929)


Heat-resistant steel of this grade belongs to the group of alloys with a limited service life and is used in the manufacture of turbine blades, as well as other parts for work at temperatures not exceeding 950 °C. The process of intense scale formation initially begins above 1,050°C.


The main requirements to the material for turbine blades are caused by the latest developments in engine designs, continuous increase in ductility, low-cycle fatigue resistance, thermal fatigue, heat resistance and resistance to gases. Material in modern engines for turbine blades must have high resistance to fracture under thermal, low-cycle fatigue, which is the main type of fracture today. The danger of failure can be exacerbated by surface reactions that occur due to softening of grain boundaries and gas corrosion.
