Werner Flanges Inc. is one of the prominent exporters and traders of ASME B16.47 Class 300 Series B Blind Flanges, which are immune to grain boundary carbide precipitation (sensitisation). We are a recognized ASME B16.47 Class 300 Series B Blind Flange Manufacturers in India, where it has better high temperature strength and mechanical strength. As a Distributor of ASME B16.47 Class 300 Series B Blind Flanges, these can be used for extended periods at elevated temperatures without compromising its corrosion resistance. ASME B16.47 Class 300 Series B Blind Flanges Dimensions has equivalent corrosion resistance to sensitisation as the low carbon version of other alloys.

Series B Class 300 Blind Flanges is an austenitic material which contains an addition of molybdenum that gives it improved corrosion resistance. Our MSS SP44 Blind Flange are particularly apparent for pitting and crevice corrosion in chloride environments. As a ASNE B16.47 Class 300 Blind Plate Flanges Dealer, these are suited to use in heavy gauge (in excess of about 6 mm) welded components.

As an Inconel Blind Flange Stockiest, these contain a small amount of titanium content, which is typically only around 0.5 %. For elevated temperature applications the high carbon variant, this Class 300 LBS Blind Flange should be employed. The austenitic structure of our ANSI B16.47 Class 300 BLRF Flange Stockholder gives excellent toughness, even at cryogenic temperatures.
