The hot rolling method is to heat the P265GH steel plate coil steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of p265gh steel plate coil rolling process is usually called semi-finished product production, also called blank production.

The black futures market is weakening. Terminal and middlemen are cautious in their inquiry and purchase, and p265gh steel plate coil merchants have different shipments. However, the factory price of p265gh steel plate coil keeps rising and the spot bottom is more supportive. The market mentality is still good. The high demand is limited, but the support from the raw material side is strong. It is expected that the p265gh steel plate coil price will be stable tomorrow.
The main function of boron in p265gh steel plate coil and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.
