1973年1月在莫斯科中央黑色金属科学研究所举行了一次苏美技术人员的座谈会.会上.L.A.Poznyak报告了苏联钼系工具钢近年的发展趋势,兹摘译如下: 最近,苏联各种高速钢的相对产量已发生了很大的变化,就在前几年.主要的高速钢是P18(18W—4Cr-1V).约占总产量的90%左右.但到1971年 A Symposium of Soviet and US Technicians was held at the Central Black Metal Research Institute in Moscow in January 1973. At the meeting, LAPoznyak reported on the recent trends in the development of the molybdenum-based tool steels in the Soviet Union. Here is an excerpt: Recently, the Soviet Union The relative yield of high-speed steel has undergone great changes, just a few years ago. The main high-speed steel is P18 (18W-4Cr-1V), accounting for about 90% of the total output. But by 1971
