Turkey produced 8.97 million metric tons of crude steel in the first quarter, with a 9.6 percent increase from the same month of last year. Iran's crude A131 grade D ship repairing steel steel production in March amounted to 6.75 million mt. up by 13.2 percent year on year. The CIS registered a A131 grade D ship repairing steel crude steel output of 25.15 million mt. falling by 0.6 on year-on-year basis, with Russia producing 17.9 million mt, down by one percent, and Ukraine producing 5.32 million mt, falling by 3.4 percent, both on year-on-year basis.Hydrogen (H) is the most harmful element in general steel such as A131 grade D ship repairing steel. 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."We can supply A131 grade D ship repairing steel, hot rolled pressure vessel plate available sizeThickness from 5mm to 150mm Width: from 1,500mm to 2,500mm Length: from 6,000mm to 12,000mmFor plates thinner than 40mm normally supply as rolled.
