Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Alloy Steel T9 Tubes, which are available with various amounts of cold work to achieve high strength and toughness by simultaneously retaining the excellent corrosion resistance of the alloy. Alloy Steel T9 Seamless Tubes has excellent resistance to hot fluoride salts in the temperature range of 1300 Degree F to 1600 Degree F (705 Degree C – 870 Degree C). To assess the resistance of welds to corrosion in Alloy Steel T9 Welded Tubes, we choose to test all – weld – metal samples, taken from the quadrants of cruciform assemblies, created using multiple gas metal arc (MIG) weld passes.

Predictably, the inhomogeneous nature of weld microstructures in Alloy Steel T9 EFW Tubes leads to higher corrosion rates (than with homogeneous, wrought products). The annealing temperature for Alloy Steel T9 ERW Tubes is 1066 Degree C (1950 Degree F), and water quenching is advised (rapid air cooling is feasible with thinner structures). Alloy Steel T9 Round Tubes is stiffer than most austenitic stainless steels, and more energy is required during cold forming.
Also, Alloy Steel T9 Square Tubes work hardens more readily than most austenitic stainless steels, and may require several stages of cold work, with intermediate anneals. On the other hand, Alloy Steel T9 Rectangular Tubes is prone to significant grain boundary attack in this boiling solution after just 3 minutes at temperatures in the approximate range 925 Degree C to 1050 Degree C.
