高强度弹簧钢的发展现状和趋势

THE TENDENCY TO HIGH STRENGTH OF SPRING STEELS AND THE EFFECT OF ALLOYING ELEMENTS

随着现代交通运输业的不断发展 ,对弹簧钢的性能要求越来越高 ,迫切要求提高弹簧钢的强度和延长使用寿命。对此 ,国内外近年来开展了大量的研究工作。评述了弹簧钢高强度化的途径和发展趋势、弹簧钢中碳和各种合金元素的作用及其合金化特点。

With the development of modern transportation industry,there are an increasing needs for weight and cost savings.Therefore,considerable efforts have been made in the development of high performance spring steels with higher strength and longer life these years.In this paper,the methods to increase the strength of spring steels and it's developing trends are reviewed.As alloying modification is also an important method for the development of high performance spring steels,the effect of alloying elements in the spring steels and the alloying features of spring steels have also been discussed.
