Behavior of Hydrogen in Super Duplex Stainless Steels

open access: yesBehavior of Hydrogen in Super Duplex Stainless Steels
Hydrogen behavior in SAF2507 super duplex stainless steel and SAF2205 conventional duplex stainless steel was investigated by means of internal friction measurement. The internal friction measurements were conducted over a temperature range from 77K to 373K by using an inverted torsion pendulum for a frequency of 1.5Hz.

Surface roughness modelling in super duplex stainless steel turning

open access: yesInternational Journal for Engineering Modelling, 2019
Super duplex stainless steels are alloys that have good corrosion resistance properties and are intended for applications in corrosive environments. Due to their chemical composition and microstructure providing high strength and thermal resistance as well as high ductility, the machinability of these alloys is difficult, resulting in longer production
