Zhejiang Mingxin Stainless Steel Co., Ltd., established in 2016, has gradually built a multi-material product system covering austenitic stainless steel, duplex stainless steel, and nickel-based alloys. 304 stainless steel offers good corrosion resistance for general industrial applications; 316L stainless steel, with added molybdenum, provides better resistance to chloride corrosion, making it suitable for coastal chemical and marine engineering. Duplex stainless steel combines austenitic and ferritic phases, offering stable performance in chloride-containing environments. The company’s products include seamless pipes, bright annealing tubes, heat exchanger tubes, coiled tubes, pipe fittings, and flanges, available in various specifications to meet the needs of petrochemical, power, semiconductor, and other industries. Testing equipment such as spectrometers and ultrasonic inspection ensure reliable material quality.
