Silver Tubes is one of the most prominent manufacturer & trader in Alloy 20 Pipe Fittings, which is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Alloy 20 Butt Weld Pipe Fittings are often specified when high strength is needed in moderate-to-large sections. Alloy 20 Butt Weld Fittings exhibits exceptional corrosion resistance in chemical environments containing phosphoric acid, nitric acid, chlorides and sulphuric acid. Carpenter 20 Pipe Fittings also has good mechanical properties at both ambient and elevated temperatures. Our ability to provide Carpenter 20 Butt Weld Pipe Fittings on a project basis is one of our strongest capabilities and is unmatched in our industry. These Carpenter 20 Butt Weld Fittings are capable of withstanding heavy duty operations at a better performance rate.
UNS N08020 Pipe Fittings use sintered carbide cutting tools and grind to side clearance and side rake angle for facing or turning operations. UNS N08020 Butt Weld Pipe Fittings is the nickel-chromium-molybdenum (Ni-Cr-Mo) that has a long history of use in the Chemical Process Industries and is known for their versatility. The combination of Molybdenum and Copper in UNS N08020 Butt Weld Fittings provide excellent corrosion resistance to reducing media, while the high Chromium content gives good oxidising resistance. These Alloy 20 Pipe Fittings are manufactured using the best quality and latest machining instruments and appliances which imparts a feel of nicely finished and smooth surface along with even thickness and firm welding rim at its cores.
