Stainless Steel 304 Flanges
Check ASTM A182 Grade F304 Pipe Flange, SS 304 Blind Flange Dimensions.
Stainless Steel 304 Flanges are made under the ASTM A182 specifications with dimensions ranging according to the ASTM and ASME standards. R.C. Metal Corporation is a leading manufacturer and supplier of the ASTM A182 F304 Flanges in all scales, types and shapes. The 304 flanges are made in ½ inches through 48 inches nominal diameter and in various pressure classes. There are different types such as the SS 304 Blind Flange based on the functionality of the flanges. The pressure classes range from 150 through 2500 and pressure numbers from PN6 through PN64.
Stainless Steel 304 Flanges
The 304 Stainless Steel Flanges are made up of an 18/8 chromium nickel alloy austenitic stainless steel. The material is strong with 205MPa minimum yield strength and 515MPA minimum tensile strength. The ASTM A182 Grade F304 Pipe Flange is suitable for the pressure vessel grade applications. The applications can be seen in the offshore oil drilling, petroleum, petrochemical, oil and gas and many other industries. The SS 304 Flanges can operate in high temperature applications up to 870 degrees Celsius operating temperatures. There are applications of ASME SA182 F304 Lap Joint Flange and other types in the heat exchangers, boilers, condensers and in pressure vessels as well.
