Material verification
Mill certificates and positive material identification for critical batches.
Marine engineering
A 316L tube alone does not create a marine-grade product. INFINEA develops the complete load path, fasteners, bearings, joints, finishes, drainage, cleaning and maintenance around the intended environment.
| Material approach | Valid role | INFINEA perspective |
|---|---|---|
| Chrome-plated steel | A bright and often grippy surface. | Corrosion protection depends on a thin coating over carbon steel. |
| AISI 304 stainless steel | A durable professional choice for many indoor and humid environments. | Less resistant to chloride-induced pitting than 316L. |
| AISI 316L stainless steel | Generally better suited to chloride-rich coastal atmospheres. | Must be correctly fabricated, passivated, assembled and maintained. |
Mill certificates and positive material identification for critical batches.
Passivation, contamination control, crevice reduction and compatible materials.
Calculations and representative proof, fatigue and functional tests.
Installation, inspection, maintenance, traceability and residual-risk information.
Responsible claims
No. Stainless steel can corrode in severe chloride environments or poor crevice design. Maintenance remains essential.
No generic approval is claimed. Vessel installation requires project-specific engineering and any applicable conformity work.
Only after completed calculations, representative testing, approved instructions and supporting reports.
