This precision-engineered welded stainless steel tube offers exceptional corrosion resistance and structural integrity for demanding applications. Manufactured from premium austenitic stainless steel grades 304 or 304L, it delivers superior performance where hygiene, strength, and environmental resistance are critical.
Features & Benefits:
✅ Premium Corrosion Resistance – Withstands oxidizing environments, chemicals, and moisture (304L minimizes intergranular corrosion in welded assemblies).
✅ High Purity & Cleanability – Ideal for sanitary applications in food/pharma with optional electropolished (Ra≤0.8μm) or pickled finishes.
✅ Consistent Strength – Meets ASTM A312 tensile strength ≥515 MPa with ≥35% elongation.
✅ Optimized Weldability – 304L’s low carbon content (C≤0.03%) prevents carbide precipitation during welding.
✅ Pressure-Rated – Sch 40 wall thickness (2.77mm) conforms to ASME B36.19 pressure requirements.
