   Physical and chemical properties:

Physical properties

Appearance:

Usually presents a silver-grey metallic luster, with a smooth surface. Depending on the processing technology and surface treatment methods, it can have different glossiness and texture.
Density: About 7.98 g/cm³, compared with other common metals, it is a material with a higher density.

Melting point:

The melting point is around 1370-1400℃, with a high melting point, which enables it to maintain a stable solid state under high temperature environment.
Coefficient of thermal expansion: In the range of room temperature to 100℃, the thermal expansion coefficient is about 16.0×10⁻⁶/℃. As the temperature changes, its size will expand or contract to a certain extent.

Magnetism:

316L stainless steel is an austenitic stainless steel. It is non-magnetic or weakly magnetic under normal circumstances, but it may produce certain magnetism after cold working deformation.

Chemical properties

Corrosion resistance:

Due to the high content of chromium (Cr), nickel (Ni) and molybdenum (Mo) elements, 316L stainless steel has excellent corrosion resistance. Chromium forms a dense protective film of chromium oxide on the surface of stainless steel, which prevents oxygen and other corrosive substances from contacting the metal matrix, thereby preventing rust and corrosion. The addition of molybdenum further improves its resistance to pitting and crevice corrosion in chloride environments, making it particularly suitable for environments that come into contact with chlorine-containing media such as seawater and salt water.

Antioxidation:

At room temperature, 316L stainless steel can resist the oxidation of oxygen in the air. In high temperature environments, it can also form a stable oxide film with good antioxidation properties, but as the temperature rises, the antioxidation ability will gradually decrease.

Chemical stability:

It has good stability to most chemicals such as acids, alkalis, and salts. In some common acidic media, such as dilute sulfuric acid and phosphoric acid, it has good corrosion resistance, but in strong oxidizing acids (such as concentrated sulfuric acid and concentrated nitric acid), its corrosion resistance will be limited to a certain extent. In alkaline media, 316L stainless steel also shows good tolerance.
Intergranular corrosion resistance: 316L stainless steel has a low carbon content and contains stabilizing elements such as titanium (Ti) or niobium (Nb), which can effectively prevent intergranular corrosion during welding or high-temperature heating, improve the material’s welding performance and corrosion resistance in some special environments.

Application:

316L stainless steel coil is widely applied across multiple industries. In the chemical industry, it is used to manufacture reaction vessels, pipelines, and storage tanks, thanks to its excellent resistance to strong acids, alkalis, and other corrosive substances. In the food and beverage sector, it is an ideal material for food processing equipment and storage containers, ensuring hygiene and safety. In marine engineering, it withstands seawater corrosion, suitable for shipbuilding and offshore structure construction. In architecture, it can be fabricated into decorative panels, curtain walls, and railings, combining aesthetics with durability. Additionally, in the medical field, it meets strict requirements for manufacturing medical devices due to its biocompatibility and corrosion resistance.
