Product Details

F51(S31803) Nut
The nut is a fastener with internal threads and used in conjunction with a screw for mechanical parts for movement or power.

BDF can offer all kinds of hot forged and cold formed nuts such as hexagon nuts, heavy hex nuts, hexagon coupling nuts, hexagon thin nuts, hexagon castle nuts, self locking nuts, hexagon domed cap nuts and other non-standard nuts according to customer drawings. The size ranges from M6-M100 in METRIC and 3/8” to 3-1/2” in INCH.
F51 alloy has the following characteristics:
Duplex stainless steel. 22% chromium biphasic (austenite / ferrite) steel (Model 2205) with medium to high strength and good resistance to normal corrosion / stress, corrosion / cracking. The alloy has the ability to withstand resistance to chloride and sulfide stress corrosion, the strength is about twice the standard austenitic stainless steel strength. When the required mechanical strength / lighter weight is required, the alloy can be successfully used as a substitute for 300 series austenitic stainless steels. F51 is easy to use many standard arc welding equipment for welding, but is not recommended for oxyethylene block welding, because there may be welding metal carbon phenomenon.
Applications:
Oil and gas industry piping, tubing and heat exchangers; pulp and paper industry bleaching equipment, liquor tanks and digesters; cargo tanks for ships and trucks; chemical processing industry pressure vessels, tanks, piping and heat exchangers; and food processing equipment.
