Technological properties
| Property | ||
|---|---|---|
| Application areas | Sanicro® 70 has good resistance to chlorine and hydrogen chloride at high temperatures and can therefore be used in the production of chlorinated hydrocarbons, e.g. in the oxychlorination reactor and the cracking furnace in vinylchloride plants. Sanicro® 70 can also be used in wet corrosive conditions, where austenitic 18Cr/8Ni steels would be susceptible to stress corrosion cracking. | |
| Corrosion properties | General corrosion: Sanicro® 70 has approximately the same resistance to organic and inorganic acids as steel of the AISI 304 type. Its resistance to sodium hydroxide is very good even at high concentrations and temperatures. Pitting: Resistance to pitting is equal to that of steel of the AISI 304 type. Stress corrosion cracking: Sanicro® 70 has very good resistance to stress corrosion cracking, particularly in chloride-bearing solution. Gas corrosion: Sanicro® 70 has very good oxidation resistance. It can be used in: Due to high nickel content the material should not be used in reducing, sulphurous atmospheres (containing hydrogen sulphide) at temperatures above 550°C (1020°F). | |
| Heat Treatment | The tubes are delivered in heat treated condition. If another heat treatment is needed after further processing the following is recommended. Stress relieving: 800-875°C (1470-1920°F), 10-15 minutes, cooling air. Solution annealing: 950-1050°C (1740-1920°F), 5-30 minutes, rapid cooling in air or water. Heat treatment after cold bending is not normally necessary, but this point must be decided with regard to the degree of bending and the operating conditions. Heat treatment, if any, should take the form of stress relieving or solution annealing. | |
| 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: Tube and pipe are normally supplied in the solution annealed and white-pickled condition. Small sizes, e.g. heat exchanger tubes, can also be supplied in the bright-annealed condition. The principal size range is shown in the figure on the right. | |
| Welding | The weldability of Sanicro® 70 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. For Sanicro® 70, 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:
