微合金碳钢作为纹理轧制带钢，特别适用于弹簧元件

Micro-alloyed carbon steel as a texture-rolled strip steel, in particular for spring elements
摘要：
The invention relates to a cold-rolled carbon steel comprising (in % by weight) C 0.63-0.85%, max. 0.40% Si, 0.20-0.90% Mn, max. 0.035% P, max. 0.035% S, max. 0.060% Al, max. 0.40% Cr, 0.003-0.010% N, preferably 0.005-0.008%, and a maximum of 0.12% of at least one micro-alloying element, the remainder being iron and steel production-related pollutants. Possible micro-alloying elements are Ti, Nb, V and optionally Zr. A carbon steel of the type is cold-rolled into texture-rolled strip steel with a high cold reduction degree and can be used in particular as a material for coiling springs or other components having spring properties.
