FIELD: metallurgy.SUBSTANCE: invention relates to the metallurgy, namely to high-strength corrosion-resistant steels for heavy duty details used in mechanical engineering, instrument making. The steel contains, wt %: carbon - 0.28-0.35, chrome - 12-14, nickel - 1.5-2, silicon - 0.5-0.8, manganese - 0.5-0.8, molybdenum - 0.4-0.8, the rest is iron.EFFECT: mechanical properties and corrosion stability are improved, the possibility for avoidance of cracks during heat treatment is ensured, the labour input of manufacture of products with the complex geometry in instrument making is reduced. |
