Incoloy 28 square plate
Incoloy 28 square plate is a nickel-iron-chromium based super austenitic stainless steel. It is made more corrosion-resistant by adding molybdenum (Mo) and copper (Cu). This makes it good for acidic environments. It is made into flat shapes by hot rolling or cold rolling. It has exact size limits. For example, its thickness can be from 5mm to 50mm. The common size is 1000mm by 1000mm. But you can also get custom sizes. Its surface can be treated by pickling, polishing, or machining.
Incoloy 28 square plate is used in tough corrosive places. For example, it is used in acid pipe flanges in the oil and gas industry. It is also used in sulfuric acid evaporator heating plates in the chemical industry. It is used in stirring parts of flue gas desulfurization (FGD) systems. It is also used in acid-resistant containers in the pharmaceutical industry. Its high corrosion resistance (especially against H₂S and chlorides) and high-temperature stability make it a key material in energy, chemical, and environmental fields. It can make equipment last longer and reduce maintenance costs.
Features of Incoloy 28 square plate
Excellent Corrosion Resistance
Incoloy 28 square plate is great in sulfuric acid, phosphoric acid, and chloride media. It resists pitting (PREN≥40) and stress corrosion cracking (SCC). It is good for acidic oil and gas environments. Copper (Cu) helps it fight reducing acids. Molybdenum (Mo) makes it better against crevice corrosion.
Mechanical and Thermal Properties
Incoloy 28 square plate has stable high-temperature strength. It can work long-term below 600℃. Its thermal expansion coefficient is lower than that of regular stainless steel. It has low work hardening during cold working. This makes it easy to stamp and weld (use ERNiCrMo-3 filler metal).
Environmental Adaptability
Incoloy 28 square plate is non-magnetic. It is good for anti-corrosion and anti-pollution in marine and chemical equipment.
Applications of Incoloy 28 square plate
Energy Industry
Incoloy 28 square plate is used for subsea pipeline flanges and lining plates in sour gas scrubbers. It fights H₂S and CO₂ corrosion.
Chemical Equipment
Incoloy 28 square plate is used to make square heating plates for sulfuric acid evaporators and reactor lining plates in phosphate fertilizer production.
Environmental Projects
Incoloy 28 square plate is used for blades and supports in flue gas desulfurization (FGD) systems. It can stand up to wet scrubbing slurry corrosion.
Custom Parts
Incoloy 28 square plate can be laser cut to make electrode plates for electrolyzers or acid-resistant liners for pharmaceutical containers.
