Chemical composition and comparison of fast cutting steel 12L14 and 12l15
12L14 and 1215 are both low-carbon fast cutting steels, which are conducive to automatic lathe turning. Their chemical composition is very close, and they are replaceable in physical properties. The biggest difference is:
1215 is an environment-friendly quick cutting steel conforming to RoHS.
The following is the chemical composition table of 12L14 and 1215:
By comparison, we found that except for the difference in lead content, other chemicals are very close. The most important difference is that the lead content of 12L14 is 0.26%, while 1215 is lead-free.
