The main function of boron in GL-DH 32 coal carrier steel plate 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.
Novel coronavirus pneumonia has been closed in recent years, and Pohang iron and Steel Co., Ltd. closed its overseas processing center in Italy, Malaysia, Philippines and India. At the request of the Italian government, all production activities will be stopped except for the necessary GL-DH 32 coal carrier steel plate products. POSCO-ITPC, an Italian stainless steel cold rolling mill near Verona in northeast Italy, is scheduled to close from March 26 to April 3.

VL E460 steel: is a structural steel plate for ships and offshore engineering."VL" stands for the abbreviation of "DNVGL", which is a standard certified by the two classification societies of DNV (Norway) and GL (Germany). The yield strength is 460. Different classification society certifications, different grade requirements and different yield strengths can be selected according to different needs.
