The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. s 700 mc steel, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.

The main function of boron in s 700 mc steel 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.

Since the beginning of this year, the global s 700 mc steel steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global s 700 mc steel steel tube industry will also suffer from the "flash collapse" of international oil prices in March.

Recently, the epidemic situation in developed countries such as Europe and the United States has become more and more serious, leading to the stagnation of economic activities in some countries, which has also affected domestic and foreign trade orders. In particular, industries such as steel, which have a long industrial chain and a wide range of industries, are more seriously affected. The development of foreign epidemic situation has different influence on the direct and indirect export of s 700 mc steel and so on steel products.
