The functioning of the duplex steel 31803 plates is characterized by heat resistance, corrosion resistance, fatigue resistance, strength, and many such impressive properties. The heat resistance it exhibits enables it to withstand excessively high-temperature conditions without letting stress corrosion affect its physical and chemical stability. Not only do they operate when temperatures rise but also effectively work in cold conditions with temperatures dropping down. The plates manifest appreciable corrosion resistance properties against a wide range of acids and liquid solvents, having the ability to operate in the presence of both sulfur and chloride ions. Fatigue due to overworking is also tackled by the plates, making them durable and versatile even in the most strenuous conditions.
Due to the variety of properties and the adaptability of the duplex plates UNS S31803 to different types of operating environments, they are famously used in heat exchangers, biofuel plants, food processing, effluent scrubbers, chemical tanks, acetic acid distillation constituents, rotors, shafts, etc.
The quality of the products can get damaged during manufacturing even when we take into consideration all the necessary precautions, this cannot be prevented but the products we deliver manage to retain their integrity because of the ample amount of tests we conduct on the products before we dispatch them.
