Does 18 10 stainless steel rust?

The many types of stainless steel will always arouse people's curiosity, 1810 stainless steel with its unique composition and performance attention.

This seemingly tough and corrosion-resistant metal material, is it really not rust?

1.1810 Composition of stainless steel

1810 stainless steel, its chemical composition contains about 18% chromium and 10% nickel, as well as some other alloying elements.

The element chromium plays a key role in the anti-corrosion properties of stainless steel. When chromium atoms react with oxygen in the air,

a dense and continuous chromium oxide (Cr₂O₃) film is formed on the surface of the stainless steel.

This film is like a strong shield, which can effectively prevent the outside oxygen,

moisture and other corrosive substances from further eroding the interior of the metal, thus giving stainless steel good corrosion resistance,

so that it can maintain a bright appearance in many environments.

2.1810 Rust of stainless steel

This does not mean that 1810 stainless steel will never rust. Under certain specific conditions, its corrosion resistance line may be breached.

For example, when 1810 stainless steel is in an environment containing high concentrations of chloride ions for a long time,

chloride ions have a strong penetration ability, which can destroy the chromium oxide film on the surface of stainless steel,

exposing the metal matrix to the corrosive medium, and then causing rust. The high salinity of the seaside air and the chlorine-containing chemical solution

in industrial production are all dangerous environments that may lead to rust of 1810 stainless steel.

3.1810 Corrosion resistance of stainless steel

If there are scratches, pits or other forms of damage on the surface of 1810 stainless steel, the chromium oxide film in these parts will be destroyed,

forming a local electrochemical corrosion of the battery. In this case, even in a relatively mild environment,

it is possible to gradually develop rust spots on the damage and spread over time.

Moreover, when 1810 stainless steel is in a high temperature environment, its crystal structure may change,

resulting in an uneven distribution of chromium elements in the metal matrix, which reduces the overall corrosion resistance and also increases the risk of rust.

4.1810 Stainless steel protection

Although 1810 stainless steel has excellent corrosion resistance under normal conditions of use, we cannot ignore those special factors that may cause it to rust.

In practical applications, we need to take appropriate protective measures according to the specific use environment and requirements,

such as surface coating, regular cleaning and maintenance, to ensure that 1810 stainless steel can maintain its excellent performance and appearance for a long time,

and maximize its role in various fields, whether it is in kitchen utensils, architectural decoration or medical equipment, etc.

Can provide reliable guarantee for our life and production.
