国外近10年,特别是80年代以来,粉末冶金不锈钢及其管材的产量迅速增加。美国不锈钢粉产量由1973年的1950吨增加到1979年的2600吨,而且正在以更快的速度发展。西欧1983年产量为6000吨,大部分为用于生产无缝钢管的气体雾化不锈钢粉,1983年水雾化粉产量比1982年增加25%,1984年估计增加10%。产量最高的是瑞典的 NybyUddeholm AB 公司,1981年不锈钢及高合金钢粉产量达8000吨。该公司开辟了用粉
Nearly 10 years abroad, especially since the 1980s, the output of powder metallurgy stainless steel and its pipe increased rapidly. The output of stainless steel powder in the United States increased from 1950 tons in 1973 to 2,600 tons in 1979 and is growing at a faster rate. In 1983, Western Europe produced 6,000 tons of gas-atomized stainless steel powder, mostly for the production of seamless steel tubes. In 1983, water atomized powder output increased 25% over 1982 and an estimated 10% increase in 1984. The highest output was Nyby Uddeholm AB in Sweden, which produced 8,000 tonnes of stainless steel and high-alloy steel in 1981. The company opened up powder
