Description

ASTM A403 WP316L Low Carbon Stainless Steel Reducing Tee

TOBO supplies ASTM A403 WP316L low carbon stainless steel reducing tees, the welding-optimized variant of 316. With maximum carbon content of 0.03%, WP316L eliminates the risk of intergranular corrosion after welding without requiring post-weld heat treatment, making it the ideal choice for field-fabricated piping systems in corrosive service.

Product Description

  • Product: Stainless Steel Reducing Tee - Low Carbon Grade
  • Material Grade: ASTM A403 WP316L (UNS S31603 / 1.4404)
  • Size Range: 1/2" - 24" (DN15 - DN600) Seamless
  • Wall Thickness: SCH10S, SCH40S, SCH80S, SCH160, STD, XS, XXS
  • Type: Reducing Tee, Seamless Butt Weld
  • Standards: ASME B16.9, ASME B16.11, ASME B16.28, MSS SP-43

Why Choose WP316L Over WP316?

FeatureWP316LWP316
Carbon Content≤0.035% (Low Carbon)≤0.08%
Post-Weld SensitizationNot SusceptiblePossible in heavy sections
Post-Weld Heat TreatmentNot RequiredRecommended for thick sections
Intergranular Corrosion TestPasses as-welded (ASTM A262)Requires annealed condition
Field WeldingIdealGood with precautions

Key Advantages

  • Weld Without Worry: Low carbon eliminates chromium carbide precipitation risk during welding, no post-weld heat treatment needed
  • As-Welded Corrosion Resistance: Maintains full intergranular corrosion resistance in the as-welded condition per ASTM A262 Practice E
  • Field Fabrication Friendly: Ideal for construction projects where post-weld annealing is impractical or impossible
  • Full Molybdenum Benefits: Retains all the pitting and crevice corrosion resistance advantages of WP316 with added weldability
  • Dual Certified Availability: Can be supplied as WP316/316L dual certified for maximum flexibility

Applications

Field-fabricated chemical piping, offshore platform process piping, pharmaceutical clean systems, semiconductor gas distribution, food and beverage processing lines, brewery and dairy piping, water injection systems, fire water ring mains
