含碳量小于0.03%的超低碳不锈钢,以其优良的抗晶间腐蚀性能,被广泛地用于化工、石油、核电、宇航等部门。超低碳不锈钢已成为不锈钢的重要分支。自发现碳有害于不锈钢的抗晶间腐蚀性能以来,冶金工作者就着手于研究降低不锈钢中碳含量的方法。因而,不锈钢冶金技术的发展与进步,都直接涉及到脱碳方法的改进。由于制氧、空分(氩气分离与净化)、直空技术的进展,从而促进了不锈钢冶金技
Ultra-low carbon stainless steel with a carbon content of less than 0.03% is widely used in chemical, petroleum, nuclear power, aerospace and other industries for its excellent intergranular corrosion resistance. Ultra-low carbon stainless steel has become an important branch of stainless steel. Since carbon was found to be detrimental to the intergranular corrosion resistance of stainless steel, metallurgists have been working on ways to reduce the carbon content in stainless steel. Therefore, the development and progress of stainless steel metallurgy technology, are directly related to decarbonization method improvement. As the oxygen, air separation (argon separation and purification), the progress of direct air technology, thus promoting the stainless steel metallurgical technology
