Stainless steel sheet is a key product of flat metal products.
Production Features
Depending on the chosen production method, flat rolled stainless steel can be hot- or cold-rolled. In the production of hot rolled sheet, steel with a high carbon content is hot rolled. Cold rolling of coiled steel produces a cold-rolled sheet with a smooth or grooved surface .
Depending on the surface treatment, stainless steel sheet is divided into three modifications:
—— matte;
—— polished;
—— mirror
Key technical parameters
Stainless steel sheets are classified into various areas depending on technical parameters such as:
1. Steel grade. Rolled products are made from various metals, but the most popular is steel with chromium-nickel additives. Resistance to corrosion processes depends on the percentage of chromium and nickel in the metal.
2. Precision manufacturing. According to this parameter, flat rolled metal can be normal or with increased accuracy.
3. Density – normal, high, especially high, improved.
4. Sheet thickness – thin and thick steel.
Sheet metal thickness
Cold rolling and hot rolling are the two main processes in the production of stainless steel sheets, and the sheets produced by them differ in thickness, performance, and application. The following is an introduction to the thickness of cold-rolled and hot-rolled stainless steel sheets:
Hot rolled stainless steel sheet
Thickness range: The thickness of hot-rolled stainless steel sheets is usually thicker, usually over 3 millimeters, and can even be produced into thicker sheets.
Production process: Hot rolling is a rolling process carried out at high temperatures. After heating, the plate is compressed by a rolling mill to achieve the required thickness.
Application field: Hot rolled stainless steel sheets are mainly used for manufacturing structural components in heavy-duty and high-temperature environments such as large mechanical equipment, ships, bridges, etc.
Features: Hot rolled sheet metal has high strength, but has a high surface roughness, which may require subsequent cold rolling or polishing treatment to improve surface quality.
Cold rolled stainless steel sheet
Thickness range: The thickness of cold-rolled stainless steel sheets is relatively thin, generally between 0.1 millimeters and 3 millimeters, and can even reach thinner specifications.
Production process: Cold rolling is a rolling process carried out at room temperature, usually on the basis of hot-rolled plates, to achieve thinner thickness and better surface quality.
Application field: Cold rolled stainless steel sheets are widely used in industries such as construction, decoration, home appliances, and automobiles, especially in situations that require high-precision and high-quality surfaces.
Features: The surface quality of cold-rolled sheets is good, with high smoothness and corrosion resistance, but compared to hot-rolled sheets, their strength and hardness are lower.
