What is a Duplex F51 Round Bar?

F51 is duplex stainless steel with a proportionate austenite ferrite microstructure. The duplex steels are categorized into three as a standard duplex, super duplex, and lean duplex. The Duplex F51 round bar is a typical duplex grade, and it is one of the most used the duplex grade bars.

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.

Attributes of the Duplex F51 Round Bar:

 There are many good attributes found in the F51 Round bars. These attributes have made our bars get greater popularity and usability among the number of industrial applications. The qualities are listed below-

  • High mechanical strength
  • High tensile strength
  • Good dimensional accuracy
  • Smoothness in finishing of surface
