Ningbo Sunwell Sealing Materials Co.,Ltd is one of the leading China monel spiral wound gasket manufacturers and suppliers with one of the famous brands, and we are also a professional monel spiral wound gasket company and factory, welcome to contact us.Alloy 400 ( UNS N04400) is a nickel-base  alloy with resistance to a variety of corrosive conditions. The alloy is most  frequently specified in environments ranging from mildly oxidizing through  neutral and in moderately reducing conditions. An additional application area  of the material is in marine environments and other nonoxidizing chloride  solutions.Alloy 400 is low in strength in the  annealed condition. For this reason, a variety of tempers are used which have  the effect of increasing the strength level of the material.Applications:  > Marine and chemical processing;  > Valve, pumps,;  > Heat ExchangersCorrosion Resistance:  > Alloy 400 is more corrosion resistant  than commercially pure nickel Monel 200 under reducing conditions, and more  resistant than refined copper alloys under oxidizing conditions;  > Alloy 400 is resistant to most  alkalies, salts, organic substances and atmospheric conditions;  > Alloy 400 is exceptionally resistant  to chloride stress corrosion cracking. Application in water, including sea and  brackish water, is a major use of the material.Chemical Analysis:CMnPSSiAlNi+CoCuFe0.100.500.0050.0050.250.02Balance32.01.0Mechanical Properties:Yield    Strength MPaUltimate    Tensile Strength MPaElongationElastic    Modules (E) Mpa24052045180Physical Properties:                Density: 8.83g/cm3SUNWELL combining the performance of Alloy  400, manufacture 400 Spiral Wound Gaskets.Welcome to contact with SUNWELL to  discuss about 400 and 400 Spiral Wound Gaskets, and Spiral wound gasket 400.
