1.4980 (X6NiCrTiMoVB25-15-2) is special corrosion, oxidation and heat resistant, precipitation hardenable austenitic stainless steel. It is designed for long-term, high strength service up to 700°C. It is non-magnetic even after severe cold deformation. The alloy has good oxidation resistance in continuous service up to 800°C. It shows the following features and properties:
15 % at 20 °C
Hardness, Brinell HB
248 [-] at 20 °C
Tensile strength Rm
895 MPa at 20 °C
Yield strength YS
585 MPa at 20 °C
Offshore & marine: Fasteners, and critical pump/valve components;Aerospace: Turbine shafts, aero engine components and high performance fasteners;Power generation: Components for gas turbines, turbine discs, and turbine blades;Other: Springs, screws, bolts, thrust nozzles and transmission parts
Very high corrosion resistance
It has good machinability and machines best in the precipitation-hardened condition when it has a machinability rating 45% that of AISI1212 free-cutting grade.
