Description

Изобретение относитс  к области изыскани  свариваемых нержавеющих сталей, предназначенных в особенности дл  работы ири отрицательных температурах (до -253°С).This invention relates to the field of finding welded stainless steels, especially designed for operating at negative temperatures (down to -253 ° C).

Известна сталь 08Х15Н5Д2Т (ЭП-410), содержаща  углерод, хром, никель, медь и титан . Однако сталь ЭП-410 имеет недостаточно высокую прочность при комнатной и отрицательных температурах, кг/мм :Famous steel 08Х15Н5Д2Т (ЭП-410), containing carbon, chromium, nickel, copper and titanium. However, steel EP-410 has an insufficiently high strength at room and negative temperatures, kg / mm:

Применение ее ограничиваетс  температурами не ниже -196°С.Its application is limited to temperatures not lower than -196 ° C.

Предлагаема  свариваема  сталь имеет повышенную прочность ири комнатной и отрицательных температурах и пригодна дл  применени  при температурах до -253°С. Это достигаетс  тем, что в ее состав введен молибден при следующем соотнощении компонентов (во/с):The proposed welded steel has increased room temperature and negative temperature and is suitable for use at temperatures as low as -253 ° C. This is achieved by the fact that molybdenum is introduced into its composition at the following ratio of components (w / s):
