Product Introduction

Super Stainless Steel 2507 Pipe with a balanced austenitic-ferritic dual-phase structure and high Cr, Mo, N content, it solves the corrosion and strength shortages of traditional 316L/304/2205 pipes. Manufactured to ASTM A790/A789 standards with strict quality testing, it ensures reliable supply for global customers. Our manufacturers can produce seamless and welded pipes to meet industry requirements. Contact us market@htpipe.com for more information and a free quote!

Super Stainless Steel 2507 Pipe Material Composition

Cr 24.0-26.0%, Ni 6.0-8.0%, Mo 3.0-5.0%, N 0.24-0.32%, C ≤0.030%, Fe balance. Ensures PREN ≥40, far exceeding standard stainless steel pipes.

S32750 Pipe Types & Finishes

Seamless (OD 6-250mm, wall 0.3-50mm) & Welded (OD 6-250mm, wall 0.5-20mm).
Finishes: Mill, AP, BA, custom.

Advantages of Our Super Duplex 2507 Pipe

2507 pipe Superior Corrosion Resistance

Excellent resistance to chloride stress corrosion, pitting and crevice corrosion. Service life 20+ years (3-5x longer than 316L/2205) in seawater, acidic oil/gas and chemical environments, reducing maintenance costs.

ss 2507 tubing High Strength & Cost-Effective

Thinner wall design cuts material, transportation and installation costs. Long service life and no unplanned downtime make it more cost-effective long-term, saving millions for large projects.

Pipe S32750 Strict Quality Control
