| Abstract: | The article analyzed the cracking reason of SCM435 low alloy cold-upsetting steel, and pointed out that inclusions, crystalloid, roiling ＆ cooling control and surfice quality are four major factors, which affects the cold-upsetting performance of cold-upsetting steel. Based on analysis mentioned above, corresponding control measures are proposed. As a result, cracking is reduced sharply and cold-upsetting performance is improved. |
