See Comparison of Duplex Stainless Steel Heat Exchanger Tubes Price with Stainless Steel Heat Exchanger tube price list
Chromium content in duplex stainless steel alloys is extremely high. In materials like the EN ASTM Duplex Cold Drawn Seamless Tube For Heat Exchanger, where chromium is the major alloyant and is present in larger amounts, the alloy produces a protective layer on the material's surface. A passivating oxide layer serves as this barrier. The reaction between the oxygen in the air and the chromium on the surface of the tubes results in the formation of this passivating layer on SAF 2205 U Shaped Tube For Heat Exchanger Tubing.
As a result, these alloys exhibit high resistance to oxidative corrosion. The yield strength of duplex stainless steel heat exchanger tubes is nearly two times higher than that of traditional austenitic stainless steels like grade 316 or grade 317, in addition to having a stronger resistance to oxidation corrosion. The Duplex seamless tube for heat exchanger can have walls that are less thick because the material is so sturdy. The mechanical characteristics will not be affected by a reduction in cross section, and the DIN 1.4462 Heat Exchanger Tubes will still be able to function to a high standard.
Duplex stainless steel alloys typically cost more money. However, because the Duplex Steel S32205 Heat Exchanger Tubes' walls may be made thinner, less material is used overall. Additionally, in some cases, the price of the S32205 Duplex Steel U Tubes may be competitive with either grade 316 or grade 317. The Duplex Steel Boiler Tube provides good resistance to both pitting and crevice corrosion in strongly oxidising and acidic conditions.
