What is Stainless Steel？
Stainless steel is a steel alloy containing at least 10.5% chromium by mass, known for its excellent corrosion resistance and high-temperature resistance. The chromium in stainless steel forms a thin layer of chromium oxide in the air and attaches to the surface, which plays a protective role against corrosion and makes it not easy to rust, so it is called “stainless steel”.
In addition to chromium, stainless steel may contain other elements such as nickel, molybdenum, titanium, and copper to enhance performance and characteristics. The addition of these elements can improve corrosion resistance, strength, formability, and other application-specific properties of stainless steel.
Stainless steel is widely used in construction, automotive, aerospace, food processing, medical and other industries in the form of plates, coils, pipe fittings, foils, etc. due to its many excellent properties such as durability, aesthetics, and hygiene.

| Category |
Introduction |
| Stainless Steel Pipe | Stainless steel pipe is a hollow tubular product, usually with a circular cross-section. Used to transport liquids and gases, with corrosion resistance and high-temperature resistance. Stainless steel tubes are suitable for chemical, petroleum, pharmaceutical, food processing, and other fields. |
| Stainless Steel Plate | Stainless steel sheets are flat sheets of metal, usually thick. Stainless steel plate has the characteristics of corrosion resistance, wear resistance, and high strength, and is widely used in construction, automobile, shipbuilding, chemical equipment, and other fields. |
| Stainless Steel Coil | Stainless steel coils are shapes rolled from stainless steel sheets and are usually sold in rolls. Stainless steel coil has similar properties to a stainless steel plate, but its coiled form makes it more flexible and convenient during processing and installation. |
| Stainless Steel Fittings | Stainless steel pipe fittings include various elements that connect and divert piping systems, such as tee and cross fittings, elbow fittings, reducers, flange series, head fittings, etc. They are used to join stainless steel pipes, providing the tightness and stability of the piping system. |
| Stainless Steel Foil | Stainless steel foil is a thin and flexible stainless steel material, usually with a small thickness. Stainless steel foil has good electrical conductivity, corrosion resistance, and high-temperature resistance, and is widely used in electronics, medical, aerospace, and other fields. |
| Stainless Steel Profile | Stainless steel profiles refer to stainless steel materials with specific shapes, such as angle steel, channel steel, round steel, square steel, etc. Commonly used in building structures, manufacturing mechanical parts, decoration, and other fields, it has good mechanical properties and corrosion resistance. |
Processing Methods of Stainless Steel
As a commonly used material, stainless steel can be formed and processed by various processing methods. Common processing methods are as follows:
Cutting: Use cutting tools, such as wire cutters, plasma cutters, or laser cutters, to cut stainless steel sheets, pipes, etc., to obtain the required size and shape.
Bending: Use a bending machine or a roller machine to bend stainless steel sheets or pipes into required angles and curves. It is often used to make pipes, angle steel, profiles, etc.
Forming: Processing stainless steel sheets or pipes into complex shapes through pressure and molds, such as concave-convex plates, curved pipes, etc. Common forming methods include stamping, deep drawing, and forging.
Welding: Joining stainless steel parts together using welding techniques. Common welding methods include arc welding (shield arc welding and argon arc welding), TIG welding, MIG welding, etc.
Polishing: Polish the surface of stainless steel by mechanical or chemical methods to obtain a smooth and bright surface effect.
Grinding: Use a grinding wheel or a grinder to grind the stainless steel surface to remove surface depressions, oxide layers, or scratches to obtain a smooth surface.
Drilling: Use tools such as a drill press, drill, or drill to drill holes in stainless steel for installing bolts, connectors, etc.
Stretching: Stretching stainless steel sheets or pipes into required shapes and sizes through stretching equipment, often used to make metal wires, metal meshes, etc.
These processing methods can be selected and combined according to specific stainless steel materials and processing requirements to meet the manufacturing and processing requirements in different application scenarios. In the actual manufacturing process of stainless steel products in our factory, it is far more complicated than the above description.
