Chemical Processing

A chemical plant in India ordered Hastelloy C276 coils (Grade: ASTM B575, 4mm thickness) from Gnee, with a total of 15 tons, for use in their flue gas desulfurization systems. The exceptional resistance of Hastelloy C276 to corrosive gases and high temperatures made it the ideal choice for the plant’s demanding, harsh environment.

Petrochemical Industry

A petrochemical refinery in Kazakhstan purchased Inconel 625 coils (Grade: ASTM B444, 5mm thickness) from Gnee, with an order volume of 20 tons, for use in high-pressure reactor units. The high-temperature strength and resistance to corrosion of Inconel 625 ensured the material would perform reliably and efficiently in the refinery’s challenging operating conditions.

Marine Engineering

A marine engineering company in France ordered Monel 400 coils (Grade: ASTM B164, 3mm thickness) from Gnee, with a total of 10 tons, for use in manufacturing offshore oil rig components. The outstanding corrosion resistance of Monel 400 to seawater and its mechanical strength made it the perfect material for the harsh marine environment.
