近年来,为了提高16MnR钢板的综合性能,国内从控制轧制和微合金化两方面进行攻关。前者已由上钢三厂等单位取得了成果。后者由重庆钢铁公司主持攻关。微合金化钢是近年来低合金钢发展的新方向之一,它的合金化原理是通过添加微量Al、V、Ti、Nb等元素与钢中残余元素(C、O、S、N等)结合,在钢中析出第二相弥散物,从而达到改善钢材综合性能之目的。重钢充分利用我国V、Ti资源的优势,通过压碳提锰及钒钛微合金化处理,使16MnR钢板的低温韧性达到
In recent years, in order to improve the overall performance of 16MnR steel, the domestic research from the rolling and micro-alloying control. The former has been made by the third unit and other steel mill results. The latter is chaired by Chongqing Iron and Steel Company. Microalloyed steel is one of the new directions for the development of low alloyed steels in recent years. Its alloying principle is that by adding trace amounts of Al, V, Ti, Nb and other elements and residual elements (C, O, S, N, Combined with precipitation of second phase in the steel dispersion, so as to achieve the purpose of improving the overall performance of steel. Chongqing Iron and Steel make full use of the advantages of V, Ti resources in our country by pressing the carbon to mention manganese and vanadium titanium microalloying, so that the low temperature toughness of 16MnR steel reached
