Hello Engineers,
I have a deal for producing small sized gearwheels and moving parts for medical instruments. In this matter I look for a steel, which will fit better for that (strong, good corrosion resistance, no
admixtures, hippo allergic etc.) Heard that 431 is ok for that, but my steel supplier offered 431 X steel. Not sure what that X will mean for the whole process. Does anyone know that material? Or you may recommend other good ones?
