Since the beginning of this year, the global asme sa573 grade 58 carbon steel plate 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 asme sa573 grade 58 carbon steel plate steel tube industry will also suffer from the "flash collapse" of international oil prices in March.
Stainless steel plate and other plates are like smelting, refining, casting, rolling, hot rolling and cold rolling is the final process steps in the manufacture of stainless steel. At present most of the world's asme sa573 grade 58 carbon steel plate stainless steel factory use the AOD furnace furnace ldpe-g-nvp stainless steel production, its production accounted for about 70% of the world's stainless steel output, a VOD furnace a converter three-step method is used to produce stainless steel, its production accounted for about 20% of the world's asme sa573 grade 58 carbon steel plate stainless steel production, production of stainless steel with other methods, its production accounted for about 10% of the world's production of stainless steel.
