The main function of boron in P355GH hardness property 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.

High-strength steel plates have the following characteristics. First, the strength is high, the bearing capacity is very good, and it is not easy to break. Second, compared with other steel plates under the same strength requirements, high-strength steel plates are lighter and thinner, which can effectively reduce the weight of structures. Third, the p355gh hardness property, high-strength steel plates are required to be safe and reliable, able to withstand complete disasters such as water, fire, earthquake, storm, etc., to protect people's safety.

High quality structural steel thick plate product p355gh hardness property dimension(mm): 40*2300*12000, 50*1780*7000, 16*2300*12000, 50*2500*10120, 55*1800*11900, 25*2300*12000, 50*2500*10060, 60*2500*8400, 60*2100*10000, 80*1920*6000, 130*2200*10000, 140*2200*10000, 55*1800*11550, 110*2320*8100, 40*1900*7350, 150*2200*10000, 45*2200*9000, 60*2500*8300, 40*2300*12000, 90*2440*12400, 125*1920*5000.

20G steel is a common carbon steel used to manufacture boilers. The performance of 20G steel is basically the same as that of 20# steel. The requirements for impact toughness, strain aging impact value and cold bending of 20G steel are increased. The yield ratio of 20G steel is slightly higher, and certain fatigue and corrosion resistance are required for p355gh hardness property steel to ensure the safe operation of boilers. 20G steel is suitable for manufacturing marine boilers, steam boilers and other boiler accessories with pressure less than 6Mpa and wall temperature less than 450 ℃.
