Recently remarkable advance of various industries, such as oil and gas exploration, petroleum refining, petrochemicals, electric power generation and LNG industries, the demand for stainless steel pipe and tubes with high corrosion resistance, high thermal resistance, and excellent properties at low temperatures has increased sharply.
"Austenitic stainless steels These steel have a wide range of applications in piping, heat exchangers, hydraulic systems and other equipment for the chemical, petrochemical, pulp and paper and food processing industries. The Mo-alloyed grades have higher resistance to general corrosion in non-oxidising acids and to pitting and crevice corrosion."
