Kanish Metals is a premier Super Duplex Steel S32750 Forgings manufacturer and supplier in Dubai, UAE. Our S32750 forgings exhibit superior corrosion resistance and mechanical properties, particularly in the chloride environment. We supply a variety of sizes and tailored-made forgings suitable for various industries like oil and gas, chemical processing, and marine. Through strict quality control measures, we guarantee that our Super Duplex Steel S32750 Forgings conform to the highest standards, providing our consumers with unequalled reliability and durability within their uses.
Super Duplex Steel S32750, also known as a “super duplex,” has approximately 25% chromium, 7% nickel, and 4% molybdenum, along with trace amounts of nitrogen. This special microstructure imparts the alloy higher resistance to pitting, crevice corrosion, and stress corrosion cracking, even under harsh conditions. S32750 has high tensile strength (usually up to 80-100 ksi) and excellent mechanical properties, such as exceptional fatigue and thermal-fatigue resistance. The hardness of S32750 forgings is usually between 250 to 300 HB, which promises high performance and endurance in harsh environments.

Yes, S32750 super duplex steel forgings are ideal for offshore and marine applications due to their excellent corrosion resistance, high strength, and resistance to pitting, crevice corrosion, and stress corrosion cracking.
Super Duplex Steel S32750 forgings are compatible with welding processes like GTAW (TIG), SMAW (Stick), GMAW (MIG), and SAW, using matching filler metals to ensure corrosion resistance and strength.
Limitations of S32750 forgings include susceptibility to hydrogen embrittlement, limited high-temperature performance, potential for welding-induced phase imbalance, and careful heat treatment requirements to maintain corrosion resistance and mechanical properties.
Super Duplex Steel S32750 Forgings are extensively employed in situations where there is a need for high strength, corrosion resistance, and high-corrosion resistance. They find extensive use in the oil and gas sector in the manufacturing of equipment for subsea, valves, and pipelines. They are also used in marine environments, for instance, in offshore platforms and seawater desalination equipment, owing to their corrosion resistance in seawater. In addition, S32750 forgings are also appropriate for chemical processing, power generation, and heat exchangers where the material is subjected to aggressive environments that demand both durability and strength.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
