在现代科学技术的发展中,钢铁材料面临着有色金属、高分子材料、陶瓷材料的严重挑战,世界年钢产量从1974年至1980年一直徘徊于七亿吨左右。合成聚合物1981年达一亿吨以上,其体积已与钢产量的体积相当;铝产量已达1600万吨;陶瓷材料也正在日新月异地进展。但是,由于综合性能,价格因素以及量大面广的工程结构材料的需要,钢铁材料仍将在今后一个相当长的时期内占主导地位。赵总理指出,在钢铁材料中要把发展合金钢、尤其是低合金钢作为一项重要的技术政策定下来。这是一个极为重要的战略决策。在这种形势下,更须革新技术,充分发挥低合金钢、合金钢具有比炭
In the development of modern science and technology, the steel materials are facing serious challenges of non-ferrous metals, polymer materials and ceramic materials. The annual output of steel in the world has been hovering around 700 million tons from 1974 to 1980. Synthetic polymers reached more than 100 million tons in 1981, and its volume has been equivalent to the volume of steel production; aluminum production has reached 16 million tons; ceramic materials are also progressing with each passing day. However, due to the combination of performance, price factors and a large volume of engineering structural materials, steel materials will continue to dominate for a considerable period of time in the future. Premier Zhao pointed out that the development of alloy steel, especially low-alloy steel, should be set as an important technical policy in steel materials. This is a very important strategic decision. In this situation, but also to innovate in technology, give full play to low alloy steel, alloy steel with carbon
