Technological properties
| Property | ||
|---|---|---|
| Application areas | The good, general high temperature corrosion resistance of Sandvik 7RE10 makes it suitable for a wide range of applications: | |
| Cold Forming | Annealing after cold bending is not normally necessary, but this should be reviewed depending on the degree of bending and the operating conditions. Heat treatment, if any, should take the form of stress relieving or solution annealing. See under "Heat treatment". Solution annealing is recommended for tubes used at temperatures above 750°C (1380°F), and when the highest possible creep strength is required in the bent tube. | |
| Corrosion properties | Sandvik 7RE10 has very good resistance to oxidation and sulphidation. It can be used in: The high chromium content of Sandvik 7RE10 makes the material resistant to oxidizing aqueous solutions. Sandvik 7RE10 also has better resistance to chloride induced stress corrosion cracking than lower alloyed steels of type ASTM 304 and 316. Sandvik 7RE10 has good resistance in cyanide melts and neutral salts melts at high temperature. The material is insensitive to "green rot" attack. | |
| Heat Treatment | Tubes are generally delivered in the solution annealed condition. If another heat treatment is needed after further processing the following is recommended: Stress relieving: 850-950°C (1560-1740°F), 10-15 minutes, cooling in air. The temperature should not be allowed to fall below 850°C (1560°F), because of the risk of sensitization. Solution annealing: 1000-1150°C (1830-2100°F), 5-20 minutes, rapid cooling in air or water. | |
| Hot forming | Hot bending is carried out at 1100-850°C (2010-1560°F) and should be followed by solution annealing. | |
| Other | Forms of supply: Seamless tube and pipe in Sandvik 7RE10 is supplied in dimensions up to 260 mm outside diameter, in the solution annealed and white-pickled condition or in the bright annealed condition. Stock sizes: Sandvik 7RE10 is stocked in sizes ranging from 13.5 mm to 168.28 mm (6") outside diameter. Additional data concerning sizes and finishes is available on request from your nearest Sandvik office. | |
| Structural Stability | Like other austenitic stainless steels, Sandvik 7RE10 has better structural stability than high alloyed ferritic steels. At temperatures between 800 and 900°C (1470-1650°F), however, the structural stability will be slightly impaired. For service in this temperature range, we recommend the use of Sanicro 31HT, which has better structural stability. | |
| Welding | The weldability of Sandvik 7RE10 is good. Suitable methods of fusion welding are manual metal-arc welding (MMA/SMAW) and gas-shielded arc welding, with the TIG/GTAW method as first choice. In common with all fully austenitic stainless steels, Sandvik 7RE10 has low thermal conductivity and high thermal expansion. Welding plans should therefore be carefully selected in advance, so that distortions of the welded joint are minimized. If residual stresses are a concern, solution annealing can be performed after welding. Welding of fully austenitic stainless steel can entail the risk of hot cracking in the welded joints, particularly under high constraint. For Sandvik 7RE10, heat-input of <1.0 kJ/mm and interpass temperature of <100°C (210°F) are recommended. A string bead welding technique should be used. Recommended filler metals:
