Steel 17-7PH is austenitic-martensitic steel with high strength, hardness, and resistance to creep, and corrosion. It is designed for aerospace components, but can also be used for other applications that require high strength and corrosion resistance, as well as leaf springs for operation at temperatures up to 316 °C. It can be used in a solut...

This paper describes the difference in the creep rate of pre-strained and no pre-strained samples of superalloy N07080. The primary strengthening mechanism of this superalloy is based on the precipitation of fine and coherent particles of the intermetallic γ' phase Ni3(Al,Ti) that ensure good creep resistance. In the case of additional streng...

More recently modified stainless steels have been used to produce various structural elements that work in complex operating conditions. Stainless steel X8CrNiS18-9 (standard EN 10088-3) is the most commonly used from the group of austenitic stainless steel in terms of machinability. This steel has high mechanical and working properties thanks to a...
