Class 150 Forged Stainless Steel Raised Face Slip-On Flanges are manufactured with 304L and 316L stainless steel for corrosion resistance. These flanges meet the dimensions and tolerances under ASME B16.5 ASTM A182 specifications. We stock these flanges in both imported and domestic (AIS) options, and our machine shop can modify ANSI/ASME flanges to spec.
