What is the culprit for the low hardness of high-precision cold-drawn tubes?
Precision cold drawn pipe is a high-precision steel pipe material with good performance in terms of shape, size and performance. However, when testing precision cold-drawn tubes, it is found that its hardness does not meet the standard requirements and is on the low side. What is the reason for this?
In addition, the cooling rate during the quenching process should also have a very large impact on the hardness of precision cold drawn tubes. Generally, the slower the cooling rate, the more the hardness of the product decreases. In order to avoid the occurrence of this kind of phenomenon, salt bath deoxidation must be strictly carried out, and the cooling temperature and time must be strictly controlled to achieve the best product.
