Coal Chemical Equipment Field
In the coal chemical equipment field, through the development of corrosion-resistant alloy materials for key equipment in acetic acid production, the challenge of applying domestic corrosion-resistant alloy materials in large-scale production units has been overcome, achieving the localization of key materials in acetic acid production. The development of domestic 330 alloy steel plates for the manufacture of muffle furnaces also promotes high-quality development of Shanghai's chemical equipment.
