Paing Tube Fittings, a reputed manufacturer and supplier based in Naypyidaw, Myanmar, offers a premium range of Stainless Steel 321 Instrumentation Tube Fittings designed for reliability, corrosion resistance, and high-temperature performance. Engineered with stabilized austenitic stainless steel, these fittings contain titanium for enhanced resistance to intergranular corrosion and carbide precipitation. They ensure secure, leak-proof, and vibration-resistant connections in instrumentation and control systems. Manufactured with precision and adherence to global quality standards, Paing Tube Fittings’ 321 Tube Fittings are ideal for use in petrochemical, power generation, aerospace, and process industries requiring superior strength and long-term performance under elevated temperatures.
Stainless Steel 321 Instrumentation Tube Fittings consist largely of iron, chromium (17-19%), nickel (9-12%), and titanium (minimum five times the carbon), which increases the resistance to precipitation of carbide. SS 321 is mechanially characterized with a tensile strength of nearly 515 MPa, 205 MPa of yield strength, and 40% of elongation. It possesses the following physical properties: 7.9 g/cm³ density, melting point of 1398-1446°C, and excellent thermal conductivity with high-temperature and corrosive resistance.
