摘要： This invention relates to a high-strength, austenitic, stainless steel, and to a method of its production. A method of producing a high-strength, austenitic, stainless steel characterised by air-melting a feedstock of super austenitic stainless steel, introducing nitrogen at 1520° C. to 1540° C. by way of electrolytic manganese containing 6 wt % nitrogen, then low carbon ferro-chrome, adding boron when the other two alloys have been fully absorbed into the molten bath, allowing the bath to cool, casting the metal at 1480° C. to 1495° C., and subsequently subjecting the castings or metal to a solution heat-treatment at 1400° C. to 1160° C. A further aspect of the invention is a high-strength, austenitic stainless steel characterised by the following chemical composition by wt %: Carbon 0.005 to 0.030 Silicon 0.03 to 1.00 Manganese 3.50 to 9.00 Phosphorous less than 0.025 Sulphur less than 0.01 Chromium 23.00 to 26.00 Molybdenum 4.00 to 6.00 Nickel 15.00 to 18.00 Nitrogen 0.50 to 1.10 Balance Fe A still further aspect of the invention is a weld rod or wire or a weld metal of the composition above definded.

摘要： A method for recovering NH3 present in a sour water stream containing odiferous compounds such as pyridines, indoles, ketones and mercaptans produced during an upgrading process for upgrading bitumen from oil sands into synthetic crude comprising treating the sour water stream in a sour water treatment unit to produce a NH3-rich stream and a H2S-rich stream; and hydrotreating the NH3-rich stream in a hydrotreater in the presence of hydrogen to remove the odiferous compounds such as pyridines, indoles, ketones and mercaptans and produce a treated NH3-rich stream.

摘要： A foundry sand composition which comprises particulate sand, aqueous sodium silicate as binder and an alkylene carbonate as hardener and which after use for moulds and/or cores in metal casting can be reclaimed for reuse by an attrition process contains before use no more than 11% by weight of alkylene carbonate based on the weight of aqueous sodium silicate and during the reclamation process has a residual moisture content of less than 0.8% by weight as determined by loss on ignition on 550.degree. C.
