EN 10028-7 Grade X8CrNiNb16-13 solution annealed (+AT)

EN 10028-7 Grade X8CrNiNb16-13 solution annealed (+AT) introduction

The austenitic steel X8CrNiNb16-13 is available in solution annealed condition as hot rolled sheet. It is a high temperature resistant special steel for application up to 800 °C. No scaling up to 800 °C. The material is resistant to embrittlement and resistant to intercrystalline corrosion, also in the sensitized condition.
Application: in turbine and steam-boiler construction (combuster lining, after heater cover, front pipes), for hot-work tools as well as for high-pressure hydrogenation quality in hydrogenation facilities at higher temperatures

Equivalent material: ASTM A240Type347H, ASME SA-240Type347H, SAE 347H, UNS S34709, ISO X8CrNiNb16-13, ISO 4961-347-77-E, ISO TS56, UNE F.3542-X7CrNiNb16-16, DIN X8CrNiNb16-13, DIN 1.4961, JIS SUSF347H, EN 1.4961
