Product Description
Ningbo Sunwell Sealing Materials Co.,Ltd is one of the leading China hastlloy spiral wound gasket manufacturers and suppliers with one of the famous brands,Website:http://www.mysealing.com, and we are also a professional hastlloy spiral wound gasket company and factory, welcome to contact us.Hastelloy C276, Alloy 276 (UNS N10276), A  Nickel-Base Alloy with Resistance in a Wide Range of Aggressive Media.Alloy 276 is a  nickel-molybdenum-chromium-iron-tungsten alloy which is among the most corrosion  resistant alloys currently available. Alloy 276 also has good high temperature  strength and moderate oxidation resistance although the alloy will eventually  form embrittling high temperature precipitates. Alloy 276 has been available  for several years and has been used in ASME Boiler and Pressure Vessel related  construction.Spiral Wound Gasket C276 Style  applications:  > Chemical and petrochemical processing;  > Flue gas desulfurizationg;  > Pulp and paper equipments;  > Industrial and municipal waste  equipments.General Corrosion:  > The alloy 276 is used in a range of  environments from moderately oxidizing to strongly reducing;  > One application is in the more  corrosive area of flue gas desulfurization system, such as outlet ducting;  > Alloy 276 compared to that of SS316 in the "GREEN DEATH" simulated  scrubber solutionGreen    Death Solution (Boiling)Corrosion    Rate, MPY (mm/a) 3162763%    Hydrochloric AcidDestroyed26.5    (0.67)> Alloy 276 is considered inert to  seawater and is used in many seawater, brine, and high chloride environments,  even at strong acid pH values;  > The high level of nickel and  molybdenum provides extreme resistance to chloride stress corrosion cracking.Chemical Analysis:CMnPSSiCrNiMoWVCoFe0.0060.1500.0050.0020.0315.50Balance16.03.500.150.106.00Mechanical Properties:                Minimum properties (ASTM B 575)0.2%    Yield Strength Minimum psi (MPa)Ultimate    Tensile Strength Minimum psi (MPa)Elongation    (% in 2'') MinimumHardness    Rb Minimum41,000    (283)100,000    (690)40100Density: 0.321lb/in3, 8.90g/cm3Specific Gravity: 8.90Specific Heat: 0.102 Btu/lb/oF,  425 Joules/kg/oKMagnatic Permeability: 1.02Electric Resistivity: 130 microhm-cm at 23  oCElastic Modulus 21oC: 29.8x106  psi (205 GPa)Descaling and Cleaning:Clean surface is required to obtain the  optimum corrosion resistance of C276. The alloy 276 content of the materials  makes descaling difficult. Stainless wire brushing or grit blasting is  advisable, followed by immersion in a mixture of nitric and hydrofluoric acids  and a thorough water rinse.C276 Spiral Wound Gaskets styles:  > SW600-276-R: C276 Strip, Graphite  Filler or PTFE Filler, 276/FG or 276/PTFE;  > SW600-276-CG: C276 Strip, Graphite or  PTFE filler, C276, SS, or CS outer ring, 276/FG-CS;  > SW600-276-CGI: C276 inner ring, C276  Strip, Graphite or PTFE filler, C276, SS, or CS outer ring, C276-276/FG-CS;  > SW600-276-RIR: C276 inner ring, C276  strip, Graphite or PTFE Filler, Without outer ring, C276-C276/FG;Other styles according to requirements.Welcome to contact with SUNWELL to  discuss about C276 and 276 Spiral Wound Gaskets, and Spiral wound gasket 276.
