EN1092-1 1.4404 Type11 WNRF Stainless Steel Forged Flange
What is EN1092-1?
EN1092-1 is a European standard for flanges. It specifically deals with circular steel flanges for use in pressure vessels, pipelines, and other applications. The standard specifies the dimensions, materials, and technical requirements for these flanges, including different types such as slip-on flanges, weld neck flanges, and threaded flanges. EN1092-1 provides guidelines for the design, manufacturing, and testing of flanges to ensure their compatibility and safety in various industrial settings.
What is 1.4404 material?
1.4404 is a material designation for a type of stainless steel. It is also known by its alternative names, such as AISI 316L or ASTM Type 316L.
1.4404 stainless steel is a low-carbon version of 1.4401 (or AISI 316). It contains a higher amount of molybdenum, which enhances its corrosion resistance properties, especially against chloride-containing environments. This makes it suitable for applications in industries such as chemical processing, marine environments, and pharmaceuticals.
The material offers excellent resistance to pitting and crevice corrosion, as well as good strength and toughness properties. It is also highly resistant to acids and alkalis, and can withstand high temperatures. Due to its advantageous properties, 1.4404 stainless steel is widely used in various industrial applications where corrosion resistance is crucial.
