Numerous factors influence the ability to extrude successfully: Two of the most influential factors are the fundamental mechanical characteristics of the steel and the die design.
Why does steel crack?
Another important physical property of steel is that it breaks only in tension and not in compression. For this reason, you should follow tension with compression whenever possible. Cracks called compression fractures are a result of the steel becoming severely brittle when overworked. Even though a crack may be present, it occurred after the steel relaxed in tension.
