Hastelloy C 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.
HastelloyC corrosion resistance
1, Can resist corrosion in any any concentration of sulfuric acid solution below 70 ℃, corrosion rate of about 0.1mm / a;
2, Corrosion rate not more than 0.1mm / a at room temperature in various concentrations of hydrochloric acid. Also less than 0.5 mm / a in the various concentrations of hydrochloric acid below 65 ℃. It will have significant impact on corrosion resistance whether there is hydrochloric acid oxygenation,;
3, The corrosion rate in hydrofluoric acid is not more than 0.25 mm / a, and the corrosion rate is not more than 0.75 mm / a under 55% H3PO4 + 0.8% HF at boiling temperature.
4, It is corrosion resistance at all temperatures or higher temperatures in dilute nitric acid, the corrosion rate is about 0.1mm / a. Have good corrosion resistance at 60-70 ℃ of any concentration of chromic acid and organic acids and other mixture, corrosion rate less than 0.125 mm / a and 0.175 mm / a;
5, It is a small number of dry and wet chlorine corrosion of one of the materials can be dry, wet chlorine exchange corrosion conditions used;
6, Can withstand high temperature HF gas corrosion, HF gas corrosion rate of 0.04 mm / a below 550 ℃ temperature, It is 0.16 mm / a when the temperature is 750 ℃.
HastelloyC alloys are widely used in industries such as nuclear power industry, chemical industry, petroleum industry, container heat exchanger, plate cooler, acetic acid and acid products, high temperature structural parts and so on.
