Custom 450 stainless steel is a martensitic precipitation-hardening stainless steel strengthened by copper and aluminum additions, providing high yield strength (typically 1310–1655 MPa depending on temper) and good corrosion resistance for aerospace fasteners, turbine components, and structural applications requiring elevated temperature performance to approximately 480°C. The H-series tempers (H900–H1150) represent increasing strength levels achieved through controlled aging, with H1150 offering maximum hardness and strength at the cost of reduced ductility, while Solution Treated condition provides baseline ductility for forming operations.
