Abstract
The invention discloses steel being good in plastic property. The steel comprises the following raw material components in percentage by weight: not more than 0.075% of carbon, not more than 0.048% of phosphorus, not more than 0.036% of surplus, 9.67-12.5% of nickel, 18.44-19.57% of chromium, 3.3-4.3% of molybdenum, not more than 0.115% of nitrogen, not more than 0.82% of silicon, not more than 2.23% of manganese, and the balance of iron and impurities. Limonite is adopted as an ironmaking raw material for the steel, and the cut-off grade of the limonite is 24-27. By adoption of the above technical scheme, the steel disclosed by the invention can be subjected to permanent deformation stably, and the integrity of the steel is prevented from being broken; meanwhile, the steel has the very strong impact-bearing capability; and accordingly, various steel materials made of the steel are very wide in application.
