Description Of Alloy 20 Pipe Fittings
Alloy 20 is a chromium-iron-nickel-based, austenitic alloy with excellent corrosion resistance in chemical environments. The alloy contains sulfuric acid and many aggressive media well. The alloy is stabilized with niobium which helps it to resist intergranular corrosion. Alloy 20 grade is also known as UNS NO8020. Also, there is a high alloy of a specific grade of stainless steel. These fittings have excellent mechanical properties, such as resistance to chloride stress corrosion cracking and sulphuric acid.
Alloy fittings mainly contain an element of nickel and copper, an alloy with traces of molybdenum and chromium content. When these chemical elements are mixed, it gives high strength and corrosion resistance properties. These fittings have chosen dimensions as per the set industrial norms. Engineers mainly select it because of its advantageous features, including resistance to corrosion and abrasion. The industrial fishing process enhances the dimensional accuracy of the alloy, and satin or bright black polish protects it from rusting.
Table of Content
Composition Of Alloy 20 Pipe Fittings:
This alloy combines carbon, manganese, silicon, sulfur, copper, nickel, chromium, iron, molybdenum, and phosphorus element.
Properties Of Alloy 20 Pipe Fittings
Alloy 20 Pipe Fittings have a higher corrosion resistance than regular steel, which is widely used because of its property. It shows good corrosion resistance, is highly suitable for fabrication, and has excellent mechanical properties. This alloy offers good resistance to corrosion, crevice corrosion, and pitting, strong resistance to stress-corrosion cracking in boiling sulfuric acid, excellent resistance to other acids such as phosphoric and nitric acids, is suitable for fabrication, and excellent mechanical properties.
Applications Of Alloy 20 Pipe Fittings
This alloy is used in the application are as follows:
• Chemical Plants
• Food processing
• Dye production
• Heat exchangers
• Mixing Tanks
• Pickling equipment
• Petrochemical plants
