1. Design
Taking a proactive stance with stainless steel design pays off in the long term. Proper planning in the design stage of stainless steel applications will minimize water penetration and reduce the potential for surface damage. Drainage holes for water should be used when possible, and cavities and crevices limited. Air flow is critical, and the design should encourage air to circulate freely throughout the application.
2. Fabrication
During the fabrication stage, it is important to prevent stainless steel from contacting iron or ordinary steel. This requires vigilance in surveying the surrounding environment including work tables, tools, storage units, steel turning rolls, and chains. Any carbon steel dust particles settling onto the stainless steel during fabrication can contaminate its surface, increasing the potential for rust formation. Furthermore, cleaning and grinding tools that have been used with carbon or low alloy steel must be kept separate from stainless steels.
3. Maintenance
Regular maintenance plays a key role in stainless steel rust prevention, as well as limiting the progression of existing rust. It is essential to remove any rust that has formed using mechanical or chemical means. The resulting grime can then be cleared away using warm water and soap. After cleaning, a rust-resistant coating should be applied.
