Expert Stainless Steel Solutions
Preserving Integrity Below Deck
Chemical Restoration & Standards (ASTM A-380)
Mechanical work is only half the battle. To fully restore the corrosion resistance of the steel, every mechanical treatment is followed by a rigorous Pickling and Passivation procedure.
Quality Assurance: All our chemical treatments are executed in strict accordance with ASTM A-380 - the global standard for cleaning, descaling, and passivating stainless steel parts and systems.
ASTM A-380 - Standard Practice for Cleaning, Descaling, and Passivation of Stainless Steel Parts, Equipment, and Systems.
Chemical Surface Treatment
Pickling & Passivation: Restoring the Chromium-Oxide Shield
Stainless steel is only "stainless" when its protective passive layer is fully intact. Contamination during operation or repair can lead to rapid corrosion. At TechYara, we specialize in high-level chemical treatments that remove impurities and reconstruct the essential chromium-oxide film.
The TECHYARA Methodology
We apply the precise level of chemical intervention required for your specific situation:
- Pickling (Descaling): A deep-level treatment using specialized acids to remove the surface layer of the metal. This eliminates deep-seated impurities, scale, and weld tints, ensuring a fresh metallurgical base.
- Passivation: A critical process using Nitric or Citric acid to accelerate the formation of the protective passive film without altering the surface finish.
Our Specialized Chemical Services:
- Pickling & Passivation: Complete descaling and restoration of corrosion resistance.
- Chemical Passivation: Enhancing the protective layer on already clean surfaces.
- Corrosion & Rust Treatment: Targeted removal of oxidation and starting pits.
- Deep Cleaning & Degreasing: Removal of hydrocarbons, cargo residues, and free irons.
- Ferrous Contamination Removal: Eliminating "free iron" to prevent galvanic corrosion.

Technical Specifications & Quality Control
Measurement, Verification, and Global Standards
At TECHYARA, quality is not subjective-it is measured. We utilize precision instruments and adhere to international protocols to verify that every surface we treat meets the exact requirements of the maritime and chemical industries.
Surface Passivity Testing
Validation of the Protective Layer
Mechanical cleaning and pickling are vital, but the only way to ensure a surface is truly "passive" is through scientific testing.
- Verification: We use advanced passivity meters to check the integrity of the chromium-oxide layer.
- The Goal: To guarantee that the stainless steel is ready for immediate contact with aggressive cargoes without the risk of flash rust or pitting.
- Reporting: Every test is documented, providing the vessel owner with a "Certificate of Passivity."
Surface Roughness (Ra) Measurements
Precision at the Micron Level
For chemical tankers and food-grade installations, the smoothness of the surface is critical for "cleanability" and preventing cargo residue buildup.
- Advanced Profilometry: We perform high-accuracy Ra (Roughness Average) measurements.
- Compliance: Ensuring surfaces meet the strict micron specifications (e.g., Ra < 0.8 µm) required for specialized cargo transport and hygienic processing.
- Optimization: Identifying areas where additional buffing or polishing is required to reach the desired finish.
