S32750 super duplex stainless steel combines austenitic and ferritic properties, delivering exceptional strength and superior corrosion resistance. This material excels in chloride-containing environments with enhanced resistance to pitting and crevice corrosion. Ideal for demanding applications including offshore engineering, petrochemical processing, seawater desalination, and heat exchanger systems.
- Over 200 tons of stainless steel seamless tube inventory (1/4"-2")
- Standard products delivered within 2 weeks
- Bright annealing process ensures clean, residue-free inner walls
- 100% eddy current testing and PMI certification
- PED, ISO, and AD2000 certified products
- Zero-defect delivery guarantee
SMLSCO implements rigorous three-step inspection: raw material re-inspection, production process control, and 100% pre-shipment inspection. All heat exchanger tubes undergo dimensional verification, surface finish assessment, mechanical property testing, PMI spectral analysis, and eddy current testing. Complete traceability records and pre-shipment documentation provided.
Multi-layered protective packaging includes individual bubble wrap or foam sleeves, plastic end caps, and secure packing in plywood crates or steel-strapped pallets for safe ocean and land transportation.
- Exceptionally high strength (nearly double that of 316L)
- Superior corrosion resistance in chloride-containing environments
- Significantly enhanced resistance to pitting and crevice corrosion
