Information

Stainless Steel 304:

Also known as an 18/8 Alloy, Stainless Steel 304 boasts approximately 18% chromium and 8% nickel. This non-magnetic grade offers superior corrosion resistance compared to lower-cost magnetic stainless steels, providing a reliable material for laboratory routines.

Corrosion Resistance Mechanism:

The presence of a minimum of 12% chromium in Stainless Steel 304 renders it rust-resistant. Chromium combines with oxygen to form a protective oxide layer, known as the passive film, which shields the steel from corrosion. However, disruptions to this film, such as scratches, can lead to corrosion if not properly addressed.

Quality Assurance:

We source our Stainless Steel 304 from traceable suppliers, ensuring its chromium composition meets specified levels. This quality assurance process safeguards against vulnerabilities like “pitting,” caused by sulphide impurities, which could compromise its corrosion resistance.

High-Temperature Performance:

Stainless Steel 304 exhibits excellent performance within a normal temperature range of -196 to +550°C. However, continuous exposure to temperatures between 550-870°C may degrade its corrosion properties, leading to pitting. In such cases, we recommend exploring our nickel or zirconium product ranges.

Cleaning and Maintenance:

Regular cleaning is essential to preserve the appearance and corrosion resistance of stainless steel. Various cleaning methods, from water and wipes to solvent cleaning, ensure effective removal of contaminants without compromising integrity. It’s imperative to avoid chloride-containing detergents or abrasive brushes, as they can damage the surface.

Note: For autoclaving and sterilisation, Stainless Steel 304 metalware consumables are resistant to sanitising agents, making them suitable for sterile applications.
