Some people find that there are cracks on the surface of 17-7PH precipitation-hardening stainless steel plate price, but do not understand the reason for the cracks. In fact, cracks are generally more likely to appear on the surface of a large number of cold steel, especially the probability of transverse cracks is relatively high.
17-7PH precipitation-hardening stainless steel plate price During the production process, the surface of the stainless steel plate will condense due to the fluctuation of the liquid level of the molten pool, the surface defects of the cold steel and the roll.
During the production process, because of the inconsistent speed, it is the main cause of cracks on the surface of the 17-7PH precipitation-hardening stainless steel plate price. In addition, during the cold rolling or bending process, the 17-7PH precipitation-hardening stainless steel plate price will be affected by Under the influence of external force, the crack deepens.
The smoothness of the surface of 17-7PH precipitation-hardening stainless steel plate price is related to the quality of the product, so if there are cracks on the surface, it will affect the sales of the product.
In order to reduce the surface cracks of 17-7PH precipitation-hardening stainless steel plate price, during production, it is not necessary to undergo hot rolling, or a little hot rolling can be done.
