Introduction
F52 is a duplex stainless steel with a 50:50 austenite, ferrite microstructure. The material combines good mechanical strength and ductility with moderate to good corrosion resistance in a variety of environments. This material is generally supplied in the annealed condition giving yield strengths in excess of 65 KSI (450Mpa), this material cannot be hardened by heat treatment but stronger surface strengths can be achieved by cold working.
This alloy is composed of 25% chromium, 4% molybdenum and 7% nickel. It has strong strength and corrosion resistance and is mainly used in chemical processing, petrochemical industry and subsea equipment. It has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient. The high chromium, molybdenum and nitrogen content makes it highly resistant to pitting, crevice corrosion and general corrosion.
In fact this alloy can be used successfully as an alternative to 300 series austenitic stainless steels in almost all applications where higher mechanical strength/lower weight is required.
Duplex Stainless F52 Applications
▪ Oil and gas industry equipment
▪ Offshore platforms, heat exchangers, underwater equipment, fire fighting equipment
▪ Chemical processing industry, utensils and pipelines
▪ Desalination plants, high pressure RO plants and submarine pipelines
▪ Mechanical components (high strength, corrosion resistant components).
