The surface quality of stainless steel can typically be impacted from foreign materials or particles of iron from manufacturing and industrial environments. The <\/span><span style=\"font-weight: 400;\">passivation of stainless steel <\/span><span style=\"font-weight: 400;\">is a method of protecting it in applications that can contribute to corrosion. There is also the added benefit of sterilization during the <\/span><span style=\"font-weight: 400;\">passivation process<\/span><span style=\"font-weight: 400;\">. The acid that the steel is emerged into decontaminates its surface.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Learn more about <\/span><span style=\"font-weight: 400;\">steel passivation <\/span><span style=\"font-weight: 400;\">services and <\/span><span style=\"font-weight: 400;\">metal finishing in Dorset <\/span><span style=\"font-weight: 400;\">with <\/span><span style=\"font-weight: 400;\">Dorsetware<\/span><span style=\"font-weight: 400;\">. <\/span><a href=\"https:\/\/www.dorsetware.com\/contact-us\/\"><span style=\"font-weight: 400;\">Contact our expert team<\/span><\/a><span style=\"font-weight: 400;\"> of electroplaters today for any enquiries, to discuss your project or to get a quote.
