Duplex F51 Round Bar
The material combines good mechanical strength and flexibility with moderate to good corrosion resistance in various environments. This material is generally supplied in the annealed condition giving yield strengths above 65 KSI (450Mpa). This material cannot be hardened by heat treatment, but powerful surface strengths can be achieved by cold working. The F51 Duplex Round Bar has 43ksi minimum yield strength and 105ksi minimum tensile strength.
Composition: The material comprises 21% chromium, 4.5% nickel, carbon, manganese, phosphorus, sulfur, silicon, molybdenum, and nitrogen in the document. This composition allows the F51 Duplex round Bars to have high performance under elevated temperatures for a long time.
