Abstract

The invention provides an extending-resisting iron alloy. The extending-resisting iron alloy comprises, by weight percent, 3%-5% of carbon, 0.5-6% of aluminum, 4%-9% of lead, 0.3%-1.4% of sodium, 3%-4.5% of lithium, 0.02%-0.08% of chromium, 0.1%-0.2% of chromium and the balance iron and impurities with the content smaller than or equal to 0.3%. The extending-resisting iron alloy achieves cold shut, cracks are reduced, ductility is good, and the elongation and impact toughness are improved.

Description

technical field [0001] The present invention relates to an extension-resistant iron alloy. Background technique [0002] Ferroalloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. Existing ferroalloys have many cracks and poor elongation. Contents of the invention [0003] In order to solve the problems raised in the above technical background, the present invention provides an extension-resistant iron alloy. [0004] The technical solution provided by the invention is: an extension-resistant iron alloy, the composition of which is composed of the following components in weight percentage: 3-5% carbon, 0.5-6% aluminum, 4-9% lead, 0.3-1.4% sodium, lithium 3-4.5%, 0.02-0.08% chromium, 0.1-0.2% chromium; the balance is iron and impurities with a content of ≤0.3%. [0005] The iron alloy is characterized in that the carbon is 3...
