S32750 (Super Duplex Stainless Steel) features a unique duplex microstructure. It combines the excellent toughness of austenitic stainless steel with the high strength and resistance to chloride stress corrosion cracking (SCC) of ferritic stainless steel. Its mechanical properties (minimum yield strength ≥550 MPa) significantly exceed those of conventional duplex steels (e.g., S32205) and austenitic stainless steels. S32750 exhibits outstanding resistance to pitting and crevice corrosion (PREN ≥ 40). This makes S32750 tube an ideal choice for handling demanding media containing chloride ions, high temperatures, and high pressures.
- Stock & Fast Delivery: Core specifications maintained in stock. From order confirmation to port shipment, delivery can be completed within 2 weeks, significantly shortening your supply chain cycle.
- Full Traceability: Raw materials sourced from certified mills, production following strict processes. Each batch includes 100% pre-shipment inspection reports covering PMI, dimensions, mechanical properties, and photographic documentation.
- Comprehensive and Reliable Certifications: Products comply with ASTM A789 standards and can provide authoritative certifications like PED and AD2000 upon customer request. They meet global entry requirements for high-end marine engineering, oil and gas, and chemical projects.
- Cost-Efficiency Optimization: Through bulk procurement of premium raw materials and efficient inventory management, we deliver highly competitive market pricing while ensuring top-tier material performance.
S32750 seamless tube is widely used in critical applications demanding exceptional strength and corrosion resistance. In the marine and oil & gas sectors, it serves as the preferred choice for subsea pipelines, platform process piping, and heat exchanger tubes, withstanding seawater and acidic media corrosion. In chemical and petrochemical applications, it serves high-temperature, high-pressure reaction systems and pipelines containing chlorides and hydrogen sulfide. Additionally, it delivers long-term stable performance in energy power (FGD systems, seawater cooling), high-concentration brine processing, and demanding mining environments, offering a cost-effective alternative to high-alloy materials.
