Abstract
The invention discloses steel good in plasticity performance. The raw materials of the steel comprise carbon, sulfur, nickel, chromium, molybdenum, nitrogen, silicon, manganese, phosphorus, iron and impurities. The steel comprises, by weight percent, smaller than or equal to 0.026% of carbon, smaller than or equal to 0.027% of sulfur, 11%-14.5% of nickel, 15.5%-17.6% of chromium, 2.4%-3.45% of molybdenum, smaller than or equal to 0.125% of nitrogen, smaller than or equal to 0.73% of silicon, smaller than or equal to 2.13% of manganese, smaller than or equal to 0.044% of phosphorus, and the balance iron and impurities. The ironmaking raw material of the steel is siderite, and the industrial grade of the siderite ranges from 26 to 28. By means of the above manner, when the steel good in plasticity performance is subjected to load external force, permanent plastic deformation can be generated while the steel cannot be damaged, various steel products can be produced and manufactured through the steel, the cost can be reduced due to the good performance of the steel, and consumption of the steel is reduced.
Description
Technical field
The present invention relates to Steel material field, particularly relating to a kind of performance is the steel that plasticity is good.
Background technology
Steel is the material of carbon containing and ferrum.Can classify according to chemical composition, including carbon steel, ordinary low-alloy steel and steel alloy.Carbon steel is different by phosphorus content, can be divided into mild steel, medium carbon steel and high-carbon steel three class, and the carbon content steel less than 0.04% claims ingot iron.Ordinary low-alloy steel is to add the steel grade of a small amount of alloying element on the basis of low-carbon (LC) straight carbon steel.Steel alloy is can be divided into low-alloy, middle alloy and high-alloy steel three class by alloying element total content difference, has good and property.Can there is the problem that plasticity is bad in existing steel, be not easy to keep after deforming upon, and impact uses.
