En 1.4903 DIN X10CrMoVNb9-1 Astm Equivalent Steel Bars
Type:Round bar
Delivery condition: Annealed black surface/Turned bright surface/Q+T
Products Description
DIN X10CrMoVNb9-1 (1.4903) steel is a high-temperature resistant, martensitic (structure of heat-treatable material used) high-alloyed chromium-molybdenum-steel, which is used for mixed-pressure turbine elements by improved properties compared with common steel (10CrMo9-10). With its higher amount of chrome and molybdenum together with nitrogen (0,03-0,07%) and vanadium (> 0,18 %) it is possible to substitute nickel it still work at more than 500°C in permanent load.
X10CrMoVNb9-1 steel is defined with the material designation type F91 according to ASTM Standard.
