Description
Предлагаема сталь принадлежит к стал м дисперсионного твердени с содержанием уготерода до 0,2%, н кремни до 3%, но отличаетс от них тем, что она дополнительно содержит азот в количестве 0,1-0,5%.The proposed steel belongs to steel m of precipitation hardening with a content of carbon to 0.2%, silicon to 3%, but differs from them in that it additionally contains nitrogen in an amount of 0.1-0.5%.
Производство предлагаемой стали осуилествл етс плавкой шихты, состо щей из малоуглеродистого железа, ферротитана и ферросилици . Азот вводитс путем пропускаь и его в гaзooбpaзнo состо нии через расплавленную сталь или путем предварительного обогащени им составл ющих шихты, например, ферротитана.The production of the proposed steel is melting a mixture consisting of low carbon iron, ferrotitanium and ferrosilicon. Nitrogen is introduced by passing it into the gas state through the molten steel or by pre-enriching with it the components of the charge, for example, ferrotitanium.
Полученна таким образом сталь обладает достаточной твердостью , красностойкостью и в зкостью н может примен тьс дл изготовлени быстрорежущих инструментов.The steel thus obtained has sufficient hardness, redness and toughness and can be used to make high-speed tools.
