Through our relationship with Foster Chemicals GmbH, we offer products for surface treatment of stainless steel. Whenever the protective surface layer of stainless steel is damaged, the steel's iron content is exposed to oxygen, and rust forms on the surface. This phenomenon always occurs during the welding process of stainless steel. To re-establish the non-rusting quality of the stainless steel, it is necessary to pickle the damaged surface area and to remove all impurities. After careful rinsing, on the resulting exposed surface, a new, strong, protective surface-oxide-layer will form. Most pickling products for stainless steel are based on nitric and fluoric acid. During the pickling process, toxic, gaseous nitric oxides (NOX) are formed by these products. Additionally, due to the high contact-toxicity of fluoric acid, these traditional products can only be used with extreme caution.
Foster Chemicals has developed a range of replacement products with strongly reduced toxicity and strongly reduced NOX-formation.
