Stainless steel is an alloy of several metals, where chromium, nickel and molybdenum play an important role. There is a so-called passive layer on the surface of stainless steel, which prevents oxidation and keeps the surface of the product or building the same for decades. When external conditions disrupt this passive layer, even stainless steel can corrode. The cause can be incorrect installation, quality selection, but also poor quality care. How to protect stainless steelFrom which adverse effects to protect stainless steel:Air with a high level of industrial exhalations, pollutants from exhaust gases, steel, cement or lime dust, sanding salt and water with a higher sodium chloride content. In do it yourself projects, stainless metal can be employed primarily in making interior and outdoor fittings for example handrails and rail. Even the Stainless steel manufacture Toronto are very popular because of the obvious benefits they give. Articles like railings can rendered support such a rail or might be adjusted onto a hand rail mount and installed on the wall apart from being an easy task to prepare and install socket. A few of the areas in places of work and homes through which stainless steel handrails are employed include decks, knee partitions and as guardrails to get balconies. Contact with objects subject to corrosion - the surface of the stainless steel product must not come into contact with objects subject to corrosion for a long time, these objects could corrode and leave stains that are difficult to remove or cause permanent damage to the stainless steel. Also long-term deposition of impurities on the surface - dust particles may contain metal or rust particles that have been released from other materials and oxidize. Proper installationWhen processing stainless steel, we pay attention to ensuring the protection of stainless steel against dust from grinding, welding and other work. Thorough cleaning and preservation after installation is also a guarantee.
MaintenanceFirst cleaning - after installation, we will perform the first cleaning using a cleaning spray designed for stainless steel. Further cleaning - maintenance of the stainless steel railing is very simple - it is enough to wash it with clean water or clean it with hot steam. Do not use any chemical additives. We clean stainless steel surfaces regularly. In an environment with less demanding conditions we clean stainless steel every 6 - 12 months, in an environment with more demanding conditions every 3 - 6 months. What to do when breaking the passive layerAfter welding and the occurrence of corrosion from the above causes, the most suitable and effective way in most cases is chemical cleaning, or pickling with subsequent passivation. What is the correct procedure for pickling?Degreasing of the surface and removal of mechanical impurities. Application of pickling agent.Effect of pickling agent.Rinse with water, or thorough mechanical cleaning with a cloth or brush under water. Surface passivationControlled formation of the passivation layer is achieved by means of a passivation agent, eg paste. These preparations are intended not only for passivation, but also for the removal of small impurities remaining after pickling, which have been released from the joints and crevices between the intermittent welds and for cleaning the surfaces from airborne corrosion. Used stainless steel gradesAISI 304 (A2) - Stainless steel for indoor and outdoor use, not suitable for aggressive environments containing Cl (chlorine), S (sulfur) and NaCl (sodium chloride). These are mainly swimming pools, wellness facilities, coastal areas, roads with heavy traffic and industrial areas, salt spray. AISI 316 (A4) - We recommend using AISI 316 stainless steel, which is resistant to them, in the above-mentioned unfavorable areas.
