Modern Methods:
Pickling of Stainless Steel
An optimal end treatment and the best preparation for electropolishing. Pickling creates clean surfaces – free from oxides, contaminants, and discoloration. Achieve purity requirements, corrosion-free surfaces free from discoloration.
Adding Perfection - Precision Engineering for Surface Optimization
At Calamo, we refine stainless steel surfaces through electropolishing, pickling, and high-purity water cleaning, ensuring consistent, high-quality results across industries. This is what our processes look like for perfect results every time.
Hot Pickling – Precision Surface Treatment for Stainless Steel
Achieving optimal surface quality requires advanced treatment methods that ensure purity, corrosion resistance, and uniformity. Hot pickling, also known as NOX treatment, is a highly effective process that removes oxides, contaminants, and discoloration, leaving behind a smooth, gray surface with enhanced durability.
Complete Surface Treatment for Maximum Performance
Unlike conventional pickling methods that target only welded and oxidized areas, hot pickling treats the entire surface, ensuring consistent results across stainless steel components. The process restores the natural chromium oxide layer, which is essential for maintaining corrosion resistance and the integrity of stainless steel.

Optimized Preparation for Electropolishing
Hot pickling is the ideal pre-treatment for stainless steel surfaces before electropolishing, ensuring a smoother, high-quality finish. It also enhances aesthetic uniformity, making it the preferred choice for applications requiring precision and cleanliness. Read more about hot pickling before electropolishing.

Post-Treatment for Maximum Purity
For applications requiring absolute purity with no water stains, high-purity water rinsing is an essential post-treatment. Calamo provides in-house high-purity water, along with cleanroom drying and packaging, ensuring flawless surface quality.
Hot Pickling of Titanium
Hot pickling when high demands for purity At Calamo, our wide range of services also includes hot pickling of titanium. Hot pickling can be applied where there are high demands for consistent metallic purity without impurities, or in applications where the requirements are to avoid inadvertent corrosion or discoloration due to embedded impurities. The surface becomes free from oxides, impurities, and discoloration, suitable for environments with high standards for purity.
