Stainless Steel 430 Flanges are made up of a material with 16% chromium, carbon, manganese, silicon, phosphorus, sulfur and iron. The material has high strength and high temperature resistance. The minimum tensile strength is 600MPa with the minimum yield strength of 260MPa. The melting point is 1510 degrees Celsius. There are different types of flanges such as the UNS S43000 Slip On Flange, weld neck flange, socket weld flange, blind flange and others.

430 Stainless Steel Flange
SS 430 Blind Flange
The slip on flange is used with seamless pipe applications. The AISI SS 430 Weld Neck Flange has a welded neck on it to allow for maximum connection surface. The socket flange and weld neck flanges keep the pipe in place during welding and they also provide extra strength to the connection. The flanges vary in specifications, standards and dimensions. The size of the flanges ranges from ½ inches to 48 inches. The SS 430 Blind Flange is useful at the end of pipes. This is used to close a pipeline. There are different types of blind flanges and they could either be connected permanently with welding or temporarily with bolts and nuts. The SS 430 pipe flange also comes in different face types and production types. The production types range as screwed, threaded, forged and plate flanges. The threaded flanges are useful in applications with threaded end pipes. The face type varies as the Stainless Steel 430 Ring Joint Type Flanges, raised face flanges and flat face flanges. The applications of these flanges are seen in general corrosive applications, water lines, oil and gas, petroleum and in structural applications as well.
