The main function of boron in S420ML steel yield strength 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.

Q690D material is a Chinese standard high-strength welded structural steel.What does Q690D stand for? Q represents the yield strength, 690 represents the yield strength value, and D represents the quality of the Q690 steel. The quality grades are A, B, C, D, and E, respectively. The impact of Grade D steel plate is﹣20°C. Q690D executive standard: GB / T1591-2008. S420ML steel yield strength, Q690D steel has high yield strength and tensile strength.

The market mentality tended to be cautious, and the market prices in most regions were adjusted in a narrow range. In terms of resources, the current market inventory continues to digest, but due to the high output of S420ML steel yield strength, and the off-season effect of downstream demand is still continuing, resulting in a slow de stocking speed. In the short term, in the case of poor shipment of high price resources and cautious market mentality, it is expected that the price of S420ML steel yield strength in the short term may be in weak consolidation operation.
