EN 10095 Grade X15CrNiSi25-21 solution annealed (+AT)
EN 10095 Grade X15CrNiSi25-21 solution annealed (+AT) introduction
X15CrNiSi25-20 shows scaling resistance up to max. 1150°C (highest application temp. in air). The steel is slightly resistant in reducing, sulfureous and carburizing athmosphere. Sigma phase embrittlement at temperatures of 600 to 900°C. Application for parts of heat-treatment furnaces, pyrolysis appliances and glass pressing forms.
