ASTM A179:Minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. Tubes shall be made by the seamless process and shall be cold drawn. ASTM A106:Carbon steel pipe for high-temperature service. These pipes are suitable for welding, bending, flanging, and similar forming operations. Hastelloy C22 N06022 2.4602 - Fushun Steel Tube

  • ApplicationsSpecificationsWorkabilityMachinabilityFabrication of Hastelloy C-22Corrosion Resistance in The As-Welded ConditionWeldingHastelloy 22 has found numerous applications in the chemical/petrochemical processing, pollution control (flue gas desulfurization), power, marine, pulp and paper processing, and waste disposal industries. At elevated temperatures, the high chromium level of Hastelloy C-22 Alloy helps it resist oxidation, carburization, and sulfidation. Since it is nickel-base, alloy 22 resists high temperature attack by halides (e.g., chlorides and fluorides). With these attributes, the alloy is widely used to protect steel tTi Sandvik Sanicro 38/4L7* Composite tubeboiler tube material. All composite tubes are subject to 100% ultrasonic hot cracking or the formation of brittle weld structures. Furthermore, excessive dilution of the fully austenitic stainless steel filler metal, during fin welding (carbon steel fin), may also lead to hot cracking or a brittle weld structure.
