Silver Tubes is a well-known whole seller of Stainless Steel UNS S32205 Pipe Fittings / Stainless Steel UNS S31803 Pipe Fittings, which are very popular ferritic-austenitic steel grades and are used for a number of applications. Stainless Steel UNS S32205 Butt Weld Pipe Fittings offer good oxidation resistance at even the highest of temperatures. At high temperatures, above 2000 Degree F, Stainless Steel UNS S32205 Butt Weld Fittings will become increasingly ferritic, becoming fully ferritic at temperatures just below the melting point. Stainless Steel UNS S31803 Butt Weld Pipe Fittings typically have 50 – 60% austenite that has formed in a ferritic matrix. When hot forming is required in Stainless Steel UNS S31803 Butt Weld Fittings, the work piece should be heated uniformly and worked in the range of 1750 Degree F – 2250 Degree F.
Immediately below this range, UNS S31803 Stainless Steel Pipe Fittings becomes substantially stronger than the ferrite and may cause cracking, a particular danger to cold edges. In the solution annealed condition from about 1925 Degree F, Stainless Steel 2205 Pipe Fittings has a microstructure with about 40 – 50% ferrite. There are many applications of Stainless Steel 2205 Butt Weld Fittings in which processing equipment is subject both to an aggressively corrosive environment and to cyclic loading. Whenever hot forming is done, Stainless Steel 2205 Butt Weld Pipe Fittings should be followed by a full solution anneal at 1900 Degree F minimum and rapid quench to restore phase balance, toughness, and corrosion resistance.
