ASTM A182, ASTM A240 Stainless Steel 446 Long Weld Neck Flanges Manufacturers
Metline is a professional manufacturer and exporter of stainless steel 446 long weld neck flanges with precision machining facilities. We produce stainless steel 446 long weld neck flanges as per ANSI B16.5, DIN Standard and EN1092-1 in size range of 1/2” to 60” NPS. The long neck guides the pipe into the flange itself and provides reinforcement that a standard weld neck flange cannot. This reinforcement is very important for safety in high pressure industrial, commercial and even residential systems. The long weld neck flanges are the best designed butt-welded flange of those currently available because of its inherent structural value. It is expensive because of the design. We produce flanges in carbon steel, stainless steel, high nickel alloys, duplex/super duplex, copper nickel, titanium and special alloys.

About 446 Stainless Steel
446 is a high chromium ferritic heat resistant alloy with excellent resistance to oxidation, sulfidation and other forms of hot corrosion. This grade is most commonly used between 1500 – 2100°F, although its elevated temperature strength is quite low. 446 is the only heat resistant alloy that will tolerate molten copper and brass. As with other high chromium ferritic stainless, 446 embrittles severely in the 700-1000°F temperature range (885°F embrittlement). 446 should not be used in this temperature range unless nearly complete loss of room temperature ductility may be tolerated. Sigma phase embrittlement occurs upon long time exposure in the 1000-1300°F range.
The grade 446 stainless steel is a ferritic, non-heat treatable stainless steel that provides good resistance to high temperature oxidation and corrosion. 446 is a ferritic stainless steel alloy melted as AOD. This alloy is non-hardenable but has excellent corrosion resistance at very higher temperatures and possesses good mechanical properties. This grade has poor ductility due to the high chromium content (roughly 25wt%). Because of the excellent oxidation resistance at high temperatures this grade is widely used as furnace parts and boiler baffles.

A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flange joints are made by bolting together two flanges with a gasket between them to provide a seal. Flanges are commonly used to connect valves into pipework making it easier for removal and maintenance. There are many common flange standards and flanges within the same standard can either be flat (commonly cast iron, ductile iron) or raised face (commonly cast steel and stainless steel).
