Since the beginning of this year, the global B750L plate zero cut 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 B750L plate zero cut steel tube industry will also suffer from the "flash collapse" of international oil prices in March.

When pouring the wear-resistant steel plate with high Mn content, the content of manganese oxide in the mold powder will increase during the pouring process. The higher the Mn content in wear-resistant steel plate, B750L plate zero cut, the more manganese oxide content in the mold powder. The higher the content of manganese oxide, the lower the viscosity of mold flux, which deviates from the initial viscosity of slag and gets the ideal value.

B750L plate zero cut, Grade P295GH chemical composition under EN10028-2:2003 is displayed as follows. Chemical composition (C: 0.08 to 0.20; Cr: ≤0.30; Si: ≤0.40; Cu: ≤0.30;Mn: 0.90 to 1.50; Mo: ≤0.08;P: ≤0.025; Nb: ≤0.020;S: ≤0.015; Ni: ≤0.30;Al: ≤0.020; Ti: 0.03; N: ≤0.012; Vi: ≤0.02). The yield Strength MPa (min) of P295GH steel plate with thickness less than 16mm is 295MPa, and the tensile strength is 460-580MPa.
