Corrosion inevitable in stainless steel

03 June 2013

Corrosion experts from UAE-based Marami Metal Plating strongly emphasize the need for stainless steel passivation treatments to prolong the process of inevitable corrosion especially in construction, oil and gas, marine and petroleum industries.

Stainless steel is an alloy of iron with various percentages of chromium, vanadium, and other metals. Stainless steel containing higher percentages of chromium forms an invisible inert or passive, self-repairing oxide film by combining with oxygen in the air on its surface. As a result, stainless steel is perceived by many to have corrosion-resistance capabilities. This oxide film however, cannot always inevitably protect all stainless steel products from the harsh environments and the natural phenomenon of rust.

According to the Managing Director of Marami Metal Plating, Rajeev Daswani, the three most common forms of stainless steel corrosion in the GCC region are Pitting Corrosion, Crevice Corrosion and Intergranular Corrosion. Michael Smith, Operations Manager at Marami Metal Plating added that stainless steel corrodes regularly unless it is being treated after operations commence.
