Description
Известные быстрорежущие стали, обладающие высокой твердостью и красностойкостью, легированы в значительных количествах дорогим и дефицитным элементом - кобальтом.Known high-speed steel with high hardness and redness, alloyed in significant quantities expensive and scarce element - cobalt.
Предлагаема сталь имеет следующий химический состав (в о/и):The proposed steel has the following chemical composition (o / i):
0.95-1,2 6,0-12,0 3,0-8,0 3,2-5,5 1,0-7,0 1,2-2,5 0,5-2,50.95-1,2 6.0-12.0 3.0-8.0 3.2-5.5 1.0-7.0 1.2-2.5 0.5-2.5
остальное.rest.
Сталь имеет высокую твердость (68-70 HRC) и красностойкость, что достигаетс легированием стали кремнием.The steel has high hardness (68-70 HRC) and red hardness, which is achieved by alloying the steel with silicon.
Стойкость резцов из стали указанного состава в 4 раза выше стойкости резцов из стали Р18 при обработке никелевых жаропрочных сплавов.The resistance of the cutters of steel of the specified composition is 4 times higher than the resistance of the cutters of R18 steel when machining nickel superalloys.
Замена части дефицитного кобальта кремнием приводит к снижению стоимости стали без ухудшени ее технологических характеристик .Replacing a part of deficient cobalt with silicon leads to a reduction in the cost of steel without deteriorating its technological characteristics.
