Heat treatment process of precision 16Mn 25mn 37Mn Precision Cold Drawn Seamless Steel Pipe
Annealing is to heat the cold-rolled precision bright steel pipe to an appropriate temperature, adopt different holding time according to the material and workpiece size, and then perform slow cooling. The purpose is to make the internal structure of the metal reach or close to the equilibrium state, and obtain good process performance and use performance. Or prepare the organization for further quenching. Normalizing is to heat the cold-rolled precision bright steel pipe to a suitable temperature and then cool it in the air. The effect of normalizing is similar to annealing, except that the resulting structure is finer. It is often used to improve the cutting performance of materials, and sometimes used to meet some requirements Parts that are not high are treated as final heat treatment.
