锰17铝2铜钒低温钢,是立足于国内资源,为代替在深冷设备上常用的高镍铬合金钢及钢材,以满足我国利用丰富的天然气资源,制造液化(-162℃)天然气容器和大力发展的制氧机(-196℃)等工业用材的需要,节约稀缺金属和镍、铬、铜,而研制的新型低温钢种。自1967年以来,经过实验室试验,两次低温(-196℃)爆破试验和扩大工业性试验,均获满意效果。已经试制冶炼此钢种近200吨。试生产工艺,基本过关。历年各批热轧钢材,均为单一的奥氏体组织,性能稳定。板、管、丝、棒各种规格品种,基本配套
Manganese 17 Aluminum 2 Copper vanadium low temperature steel is based on the domestic resources, instead of commonly used in the cryogenic equipment, high nickel-chromium alloy steel and steel to meet our rich use of natural gas resources, manufacturing liquefied (-162 ℃) natural gas containers And the development of oxygen generator (-196 ℃) and other industrial timber needs, saving scarce metals and nickel, chromium, copper, while the development of new low-temperature steel. Since 1967, after laboratory tests, two low-temperature (-196 ℃) blasting tests and the expansion of industrial tests, are satisfactory results. Trial production of nearly 200 tons of this steel. Trial production process, the basic clearance. Over the years batches of hot-rolled steel, are a single austenite, stable performance. Plate, tube, wire, bar variety specifications, the basic package
