Stainless steel push-in fittingsare not rust-free, but relatively less prone to rust. While ordinary steel rusts after being exposed to air for weeks or months, stainless steel push-in fittingscan last for years or decades, it is also one of the important works to prevent stainless steel push-in fittings from rusting in time.

Why do stainless steel push-in fittingsrust?

First is the material, because the element content is different, stainless steel is divided into several series, the Common 2 and 3 series, the typical representative is 201 and 304. The higher the first digit, the higher the chromium and nickel content and the greater the corrosion resistance, as chromium and nickel is oxidized to form a dense oxide film that prevents further oxidation.

Secondly, it is related to the environment, mainly can not contact strong oxidizing substances, especially acid. There is chlorine in tap water and seawater, and hydrogen ionized with water forms hydrochloric acid that can corrode stainless steel, so even if the stainless steel is used in the piers of the sea-crossing bridge, it has a useful life, because the penetration of chlorine ions is very strong, can pass through concrete to reach stainless steel.

High temperature is also a factor in the rusting of stainless steel push-in fittingsbecause it promotes corrosion reaction. In the cleaning process, often heating, soon after washing will be found that there is rust, and at room temperature cleaning, often there will be no rust.

For stainless steel push-in fittingsthat have been rusted, it is suggested to use a rust remover, which has selectivity, only reacts with rust, and the non-rust parts can not be destroyed, and can keep the original luster. In the high-temperature cleaning process, it is recommended to add 2% -5% of the water-based rust inhibitor, it can protect stainless steel in the cleaning process and a few months after the rust. If there is a shipping link, it is recommended to use high-moisture desiccant or clay desiccant to remove water, no water, even if the sea air salt accidentally into the packaging, corrosion reaction is not easy to occur.

To have a long service life, it is very important to select high-quality stainless steel push-in fittingsin addition to timely rust removal.
