Description
DIN X20CrMo13is stainless, heat resistant steel up to temperature of 550oC. Steel is resistant to water with a low chlorine content in fine-machined or, better still, polished condition.

Applications
Owing to its greater high-temperature strength and corrosion resistance - resulting from the addition of molybdenum - DIN X20CrMo13is used for shafts and blades in water and steam turbine systems. One special field of application is for bedknives in the cellulose industry.
