Stainless steel grade F55 has excellent corrosion resistance to a wide range of areas, especially resistance to pitting and crevice corrosion in seawater and other chloride containing environments, with critical pitting temperature that is more than 50°C (122°F). This material is known to also have high strength and extended lifecycle. It is 10% lighter than grade 316 steel, ideal for sub-zero service, and more cost effective than nickel alloys. Stainless steel grade F55 can be easily machined and welded. The following datasheet provides an overview of stainless steel grade F55. Chemical ComPOSTTTIONThe chemical comPOSTTTION of grade F55 steel is outlined in the following table.
Mechanical PropertiesThe mechanical properties of grade F55 steel are displayed in the following table.
Other DesignationsEquivalent materials to grade F55 are EN 10088-3 1.4501 and ASTM A182 F55. ApplicationsGrade F55 steel is widely used in the following applications:
