工艺试验是确定某一钢材是否能适应在一定的加工工艺过程中的变形能力,也就是模拟性试验。工艺性能试验的特点,一般不计其受力大小,仅使钢材达到规定变形后,观察其变形处的表面状态,如有无裂缝、裂口或裂断等。所以工艺性能试验能给钢材在实际加工工艺的条件下提供可靠的试验数据,同时也反映出钢材质量。但是工艺性能试验仅仅是钢材试验项 Process test is to determine whether a certain steel can adapt to the deformation process in a certain process, that is, simulation test. The characteristics of process performance test, generally do not count the size of its force, only to achieve the required deformation of steel, observe the deformation of the surface state, such as the presence of cracks, cracks or cracks. Therefore, the process performance test can give the steel in the actual processing conditions to provide reliable test data, but also reflect the quality of steel. However, the process performance test is only a steel test item
