摘　　要：钢中硫含量及大于20μm的带状夹杂物是影响气瓶钢质量的主要因素,特别是带状硫化物。随着硫含量的增加严重恶化薄板的深冲性能。同时,探讨了夹杂物与塑性断裂的关系。The main factors which affect the quality of gas vessel steel are sulfur content and the inclusion whieh is larger than 20 μm in size. Spectal sulphide plays an importent role. The deep-drawing property of sheet steel is seriously worsened with the increase of sulfur content In addition, the relationship detween inclusion and deformation failure is discussed.
