Factors affecting flame cutting of marine grade DH36 steel plate

Try to use marine grade DH36 steel plate high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the marine grade DH36 steel plate temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

In the first quarter, marine grade DH36 steel plate, crude steel output in Asia amounted to 315.15 million mt, falling by 0.3 percent, with 234.45 million mt produced by China, up 1.2 percent, 24.36 million mt produced by Japan, decreasing by 2.4 percent, 27.5 million mt produced by India, falling by 5.3 percent, and 16.94 million mt produced by South Korea, down by 4.8 percent - with all comparisons on year-on-year basis.
