Description

Данные по сопротивлению коррозионному растрескиванию высокопрочной мартенситностареющей стали ЭП-637 (ав 210 кг/мм), обработанной по известному и предлагаемому способам приведены в таблице.Data on the resistance to corrosion cracking of high strength maraging steel EP-637 (AV 210 kg / mm), processed according to the known and proposed methods are shown in the table.

ТаблицаTable

Из сравнени  данных видно, что описываемый способ значительно повышает сопротивление коррозионному растрескиванию стали.From a comparison of the data it can be seen that the described method significantly increases the resistance to corrosion cracking of steel.

Предмет изобретени Subject invention

Способ обработки мартенситно-стареющих сталей, включающий Предварительный нагрев до температуры выше температуры закалки, охлаждение, многократную закалку, старение и поверхностное упрочнение, отличающийс   тем, что, с целью повышени  сопротивлени  .коррозионному растрескиванию стали, перед старением дополнительно провод т поверхностное упрочнение.A method of treating martensitic aging steels, including Preheating to a temperature above the quenching temperature, cooling, multiple hardening, aging and surface hardening, characterized in that, in order to increase the resistance to corrosion cracking of the steel, additional surface hardening is carried out before aging.
