MSI Fittings is one of the leading and prominent industries that is supplying and manufacturing premium quality Monel 400 Flanges. Our professionals precisely design and develop all types of flanges using a standard quality raw material and following all the set manufacturing norms. The raw material is tested stringently before they use to ensure higher efficiency and long-lasting working life of flanges. We are producing these flanges using Nickel copper-based Monel 400 alloy that has higher corrosion resistance in critical conditions. Our high-grade Flanges are in high demand because of their dimensional accuracy and quality standard. This alloy is highly resistant to steam, seawater, caustic solutions, and salt. We are manufacturing Monel 400 Flanges that exhibit characteristics like excellent corrosion resistance, good weldability, and formability. These flanges can easily sustain in elevated and cryogenic temperature environments.

MSI Fittings has a highly developed manufacturing firm with an automated facility for conduction fabrication and quality testing procedure of Monel 400 Flanges. As we do not compromise in the quality, we pass each flange through stringent quality tests to test various qualitative parameters. Our quality assurance team performs this testing process as per the guidelines of international quality standards. With adequate material and standard packaging methods, we maintain the quality of flanges and protect the flanges from rust and damage during the shipping. We ensure safe and doorstep delivery of Monel 400 Flanges to specified locations of our valued clients within the shortest delivery time.

Applications that deal with the marine environment are required to be resilient to the effects of saltwater. After all, the concentration of salt in marine water is about 3.5%, enough to corrode ordinary steels with no protective surface treatment. Yet some alloys like the Monel 400 Flanges can perform well in marine environments because of their chemical composition. With the content of copper ranging between 28% to 34%, it is referred to as a superalloy for its good corrosion resistance properties. Preferred by many a Monel Flanges Manufacturer in India, this alloy exhibits high tensile strength making it a commercially viable option for marine engineering purposes. The WNR 2.4360 Reducing Flange is resistant to chloride stress corrosion cracking, which is a common issue in marine environments. Like many nickel-containing alloys, the performance of this alloy supersedes many conventional stainless steel alloys at elevated temperatures. The functionality of the ASTM B564 Uns N04400 Pipe Flange is so great that its mechanical properties remain unaffected despite exposure to a temperature as high as 1000° F. Usually, the production of these components is made possible by annealing. The drawback of this annealing this alloy is that the strength of the Nickel Alloy 400 Forged Flanges remains low. It is possible to improve this characteristic of the alloy by simply using tempers. Tempers improve the strength and impact strength of the material. Though the high content of copper would indicate that the alloy would be attacked by acids, in a de-aerated condition, the Class 150 Monel 400 Rtj Flange shows resilience to both hydrochloric acid and hydrofluoric acid. It is not recommended to use the alloy in environments that contain solutions of ammonia or nitric acid. This is because both these solutions rapidly disintegrate the Monel 400 Blind Flange due to its copper chemistry.
