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.
347 alloy has the following characteristics:
347 alloy = 0Cr18Ni11Nb containing Nb to improve resistance to intergranular corrosion, with strength, plastic does not reduce. So that the thickness of the material is reduced. As a structural strength component. Has a good resistance to crystal corrosion properties of austenitic stainless steel. In the acid, alkali, salt solution has good corrosion resistance, in the 800 ℃ below the air has good oxidation resistance and weldability. 347 alloy has excellent high temperature stress breaking performance and high temperature resistance to creep performance stress mechanical properties are better than 304 stainless steel.
The steel has excellent forming and welding qualities and excellent toughness even at cryogenic temperatures.
