What material is stainless steel plate

Metal material

Stainless steel plate is a metal material. Specifically, it is an alloy of iron, with its main component being iron and contains other substances such as carbon. Stainless steel plates are widely used in various fields due to their unique properties. The following are detailed instructions on the material of stainless steel plates:

‌Material Classification

Stainless steel plates are metal materials, not synthetic materials, silicate materials or natural organic polymer materials. It is an alloy with iron as its main component, usually containing elements such as chromium and nickel to enhance its corrosion resistance and mechanical properties.

‌Main ingredients

‌Iron‌: The main component of stainless steel plates, providing basic metal properties.
‌Chromium‌: Usually the content is above 10.5%, forming a protective layer of chromium oxide to prevent rust.
‌Nickel‌: Improves toughness and corrosion resistance, commonly found in austenitic stainless steel.
‌Other elements: such as carbon, molybdenum, titanium, etc., are used to improve specific properties, such as high temperature resistance or work hardening properties.

Performance Features

‌Corrosion resistance‌: Stainless steel plates can resist corrosion by weak media such as atmosphere, steam, and water. Some types (such as 316 stainless steel plates) can also withstand the corrosion of chemical media such as acids, alkalis, and salts.

Mechanical properties: High plasticity, toughness and mechanical strength, suitable for a variety of processing and manufacturing needs.
‌High temperature resistance‌: Some types (such as 321 stainless steel plates) have better high temperature strength and grain boundary corrosion resistance due to the addition of titanium.

‌Common Types

304 stainless steel plate‌: general-purpose stainless steel, excellent anti-rust performance, widely used in daily and industrial fields.
‌316 stainless steel plate‌: Due to the addition of molybdenum, corrosion resistance and high temperature strength are better, and are suitable for harsh environments.
‌321 stainless steel plate‌: Added titanium elements, outstanding high temperature resistance, and is suitable for high temperature environments.

To sum up, stainless steel plate is a metal material with iron as its main component. It gives it excellent corrosion resistance and mechanical properties by adding elements such as chromium and nickel, and is widely used in industries, construction, medical and other fields.
