Description
Дефицитность вольфрама, вл ющегос основной составл ющей быстрорен ущей стали, заставл ет изыскать такие составы стали, кото )ые вовсе не содержат вольфра.;а или содержат его в малом ко.-щчестве и вместе с тем обладают нроизводительностью нормальной быстрорежущей стали. Р д марок стали - замените. быстрорежущей стали - уже известен. Однако одни из них, не устуна по производительности быстрорежущей стали обычного состава, содержат не менее дефицитный молибден, другие стали - без молибдена - обладают малой производительностью .The scarcity of tungsten, which is the main component of the fast-moving steel, leads to finding such steel compositions that do not contain tungsten at all. Rd steel grades - replace. high speed steel - already known. However, some of them, not ustuna on the performance of high-speed steel of the usual composition, contain no less deficient molybdenum, others have - without molybdenum - have low productivity.
