Description

Примен емые в т желом машиностроении конструкционные свариваемые стали обладают недостаточно высоким пределом текучести.Structural weldable steel used in heavy mechanical engineering has an insufficiently high yield strength.

Описываема  конструкционна  сталь дл  изготовлени  крупногабаритных пресс-формовочных штампов и контейнеров, содержаша  кремний , марганец, хром, никель, молибден и ванадий, обладает высоким пределом текучести, хорошей свариваемостью и более высокой прочностью и теплостойкостью. Достигаетс  это удачным выбором легирующих элементов и их соотношением, характеризующимс  низким содержанием углерода и карбидообразуюших компонентов.The described structural steel for the manufacture of large-sized press-dies and containers containing silicon, manganese, chromium, nickel, molybdenum and vanadium, has a high yield strength, good weldability and higher strength and heat resistance. This is achieved by a good choice of alloying elements and their ratio, characterized by a low content of carbon and carbide-forming components.

Описываема  сталь содержит (в процентах): 0,12-0,18 углерода; 0.17-0,37 кремни , 0,4-0,6 марганца, 1,5-1,8 хрома, 1,3-1,5 никел , 0,5-0,6 молибдена, 0,2-0,3 ванади  и не более чем по 0,03 серы и фосфора.The described steel contains (in percent): 0.12-0.18 carbon; 0.17-0.37 silicon, 0.4-0.6 manganese, 1.5-1.8 chromium, 1.3-1.5 nickel, 0.5-0.6 molybdenum, 0.2-0.3 vanadium and not more than 0.03 sulfur and phosphorus.

Критические точки стали: Aci 790° и Асз 880°; температура нормализации 920-930°.Critical points of steel: Aci 790 ° and Asz 880 °; normalization temperature 920-930 °.

Сталь хорошо свариваетс  и после нормализации при 920-930° и отпуска при 600-650° обладает пределом прочности 118 кг/жж, удлинением MVo и ударной в зкостью 5 кгм/сл.Steel is well welded and, after normalization at 920-930 ° and tempering at 600-650 °, has a tensile strength of 118 kg / lg, an elongation of MVo and a impact strength of 5 kgm / sl.

Сталь предназначаетс  дл  изготовлени  контейнеров, гор чего прессовани , пресс-формовочных штампов, высокопрочных сварных и несварных крупногабаритных деталей ответственного назначени  и сосудов , работаюших под высоким давлением.The steel is intended for the manufacture of containers, hot pressing, molding dies, high-strength welded and non-welded large-sized parts of responsible designation and high-pressure vessels.

В зависимости от условий применени  и термообработки сталь при .нормальной температуре обладает следуюшими минимально гарантируемыми механическими свойствами:Depending on the conditions of use and heat treatment, the steel at the normal temperature has the following minimum guaranteed mechanical properties:
