1215AN易切钢硫含量高，切削加工性能好，塑性高，强度更高。
HSXZ12延伸率达到12%，V形冲击功达到40J。
ETG100 是一个具有高强度的易切削钢材料。它是碳钢成分，不含铅，但具易加工性能特别好，适用于高速CNC加工，并具有良好的焊接性能。
它的钢材主要是棒材，用于加工各种轴类零件。由于此材料的内外部各个截面强度一致，所以可以加工成各种形状的零件，并还能保持很高的强度。
S45CL该钢含碳量在0.4%以上，耐磨性优良，但延展性减少，淬火易变形和开裂，故热处理极为重要，且回火后无需急冷，因其没有第二类回火脆性。通过对该钢实行球化处理，可以改善这类碳钢的切削加工性能。广泛用于机械制造
