Steel, Corrosion and Heat Resistant, Sheet, Strip, and Plate 15Cr 25.5Ni 1.2Mo 2.1Ti 0.006B 0.30V Multiple Melted, 1800\mDF (980\mDC) Solution Heat Treated, Welding Grade Precipitation Hardenable
This specification covers a precipitation-hardenable, corrosion and heat resistant steel in the form of sheet, strip, and plate. These products have been used typically for parts requiring high strength up to 1300 \mDF (704 \mDC) and oxidation resistance up to 1500 \mDF (816 \mDC), particularly those which are welded and then heat treated to develop required properties, but usage is not limited to such applications.
