| 压力加工 | shaping (【技】成形：借助外力或工具将材料加工成具有一定形状、组织结构和力学性能的坯体或成品的工艺过程。钢产品的成型方法有锻造、铸造、轧制、挤压、冲压、焊接等。: A metal with a low elongation would crack when subjected to deep drawing and would be unsuitable for making, say, the body of a fire extinguisher or a shell case because the metal used is subjected to considerable deformation during shaping. 低延伸率金属在进行拉深加工时会产生断裂，也就是说低延伸率金属不适于制造灭火器壳体类制品，因为在成形加工时所使用的金属要承受巨大的变形。) |
