Werner Flanges Inc. is one of the prominent exporters and sellers of ASME B16.47 Class 400 Series B Blind Flanges, which offers good oxidation resistance. We are a known ASME B16.47 Class 400 Series B Blind Flange Manufacturers in India, these are a non – stabilised low carbon high alloy austenitic material. The addition of copper to these VALVE gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid. As a Distributor of ASME B16.47 Class 400 Series B Blind Flanges, these are also highly resistant to chloride attack – pitting / crevice corrosion and stress corrosion cracking.

ASME B16.47 Class 400 Series B Blind Flanges Dimensions is non – magnetic in all conditions and has excellent weldability and formability. The austenitic structure of Series B Class 400 Blind Flanges also gives this grade excellent toughness, even down to cryogenic temperatures. As an Alloy Steel Blind Flange Exporter, it does have very substantial contents of the high cost ingredients nickel and molybdenum.

Many of the applications in which this grade has previously performed well can now be fulfilled at lower cost by Class 400 LBS Blind Flange, so it is used less commonly than in the past. Similar but not necessarily identical properties of ASME B16.47 Class Stainless Steel BLRF Flange are specified for other products in their respective specifications.
