Hydrogen (H) is the most harmful element in general steel such as pickled steel sheet s420mc. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.

According to the separate performance report released by India's Jindal stainless steel (Sisal) Co., Ltd.

It can be predicted that in 2019, the national steel market quotation will not appear unilateral quotation, rebar pickled steel sheet s420mc steel main contract price of the largest shock range (the lowest price to the highest price), it is possible to reach as much as 1000 yuan this is the New Year's Chinese steel market quotation of the first characteristic. The second characteristic of Chinese steel market quotation in 2019 is that the average pickled steel sheet s420mc steel price of the whole year is roughly flat with the level of the previous year, or it is to rise somewhat, generally there will be no annual average price decline.
