一种时效后抗拉强度能够达到1800Mpa以上,维氏硬度达540以上的新型时效马氏体不锈钢CrNiMoTi,近日在东北特钢集团精密合金公司研制成功。该产品的成功研制对满足航空工业等特殊领域的需要将起到重要作用。新型时效马氏体不锈钢CrNiMoTi是精密公司科研人员在美国卡彭特公司生产Custom465的基础上,经过反复研究试验,在调整有关成分后研制成功的。为了保证此产品有更好的时效性能,精密公司科研人员将C的标准定为小于0.010%,同时很好地解决了真空冶炼的脱氧问题,使产品实物碳含量达到0.006%。通过严
A new type of aging martensitic stainless steel CrNiMoTi with tensile strength up to 1800Mpa and Vickers hardness of over 540 has been successfully developed recently by Dongbei Special Steel Group Precision Alloy Company. The successful development of this product will play an important role in meeting the needs of special fields such as aviation industry. The new aging martensitic stainless steel CrNiMoTi is a precision company researchers in the United States Carpenter Custom465 produced on the basis of repeated research tests, after the adjustment of the relevant components of the successful development. In order to ensure that this product has better aging performance, precision company researchers set the standard of C to less than 0.010%, and solved the problem of deoxidation by vacuum smelting at the same time, making the real carbon content of the product reach 0.006%.
