Description
3 Unmatched Value Propositions
Weld Zone Immunity
No post-weld carbide precipitation even at 450–800°C (per ASME Section VIII).
Multi-Industry Compliance
Meets FDA 21 CFR, EHEDG, and 3-A Sanitary Standards for food/pharma surfaces.
Adaptive Surface Tech
Electropolished (Ra ≤0.25µm) or passivated (Citric/Nitric acid options).

Industry-Specific Mastery
1. Food & Beverage
Fermentation tanks (pH 3–12 resistant)
Conveyor belts for salty/sugary products
2. Medical Device Manufacturing
MRI machine frames (non-magnetic after annealing)
Sterilizable surgical tray components
3. Chemical Transport
Rail tanker liners for liquid fertilizers
Ethanol storage dividers
4. Architectural Longevity
Coastal balcony railings (5km+ from shore)
Underground parking ventilation ducts
Client Validation
Amsterdam Brewery Co.: “304L electropolished plates slashed tank cleaning time by 35%.”
Singapore Pharma Hub: “Zero contamination in 200+ autoclave cycles.”
Texas Chemical Logistics: “Replaced 316L in urea transport—saved $120k annually.”
Fabricator-Centric Support
Q: How to restore corrosion resistance after welding?
A: Optional local passivation (20% nitric acid dip, 30min @ 50°C).
Q: Maximum operating temperature for continuous service?
A: 870°C (intermittent) | 425°C (continuous with <0.5% scaling).
Q: Can 304L replace 316L in coastal architecture?
A: Yes beyond 5km from shoreline—use 316L within 2km.
Q: Minimum order for custom passivation?
A: 500kg for citric acid | 1 ton for nitric acid treatment.
