Material Properties
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.
Product Advantages
- 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.
Application Scenarios
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.
Frequently Asked Questions
Q1: What is the standard delivery lead time for this product? Is it available from stock?
A1: For S32750 material, we maintain strategic inventory for common sizes (1/4"-2") to enable rapid response. When stock is available, shipment can be arranged within 2 weeks from order confirmation through inspection, packaging, and port readiness, effectively safeguarding your project schedule.
Q2: How do you ensure the quality of S32750 tubes?
A2: We implement a rigorous "three-step inspection" system: 1) Verifying raw material certificates of analysis; 2) Monitoring the production process; 3) Conducting 100% dimensional, surface, and PMI tests prior to shipment. Our transparent quality control process guarantees product integrity.
Q3: What packaging is used? How is damage and corrosion prevented during long-distance sea transport?
A3: To ensure optimal delivery condition, we employ industrial-grade rust-proof packaging. Each tube end is sealed with plastic caps, the tube body is wrapped in plastic film, and the entire assembly is securely fastened within reinforced wooden cases. This packaging effectively prevents impact, moisture, and chloride ion contamination during transit, ensuring products arrive as pristine as when manufactured.
