Audited Supplier Stainless steel is an alloy steel whose main component is iron, while containing at least 11% chromium, as well as other elements such as nickel, molybdenum, manganese and so on. The following are some properties of stainless steel:
Alloy 304 a T-300 series stainless steel austenitic, which has a minimum of 18% chromium and 8% nickel. Type 304 has a maximum carbon of 0.07% . It is the standard "18/8 stainless" that is commonly found in pans and cooking tools. Alloy 304 is the most versatile and widely used alloy in the stainless steel family. Ideal for a wide variety of home and commercial applications, Alloy 304 exhibits excellent corrosion resistance and has a high ease of fabrication, outstanding formability. The austenitic stainless steels are also considered to be the most weldable of the high-alloy steels and can be welded by all fusion and resistance welding processes.
Corrosion resistance: Stainless steel is known for its excellent corrosion resistance. The chromium element reacts with oxygen to form a dense oxide film (chromium oxide layer), which prevents further oxidation and corrosion on the surface of the steel, making the stainless steel resistant to the erosion of most chemical media. This makes stainless steel widely used in environments containing water, gases and chemicals.
High temperature performance: stainless steel maintains good performance at high temperatures and can maintain structural stability and strength for a long time. This makes stainless steel suitable for high-temperature processes and applications, such as petrochemical, energy production and other fields.
Mechanical properties: Stainless steel has excellent mechanical properties, including strength, hardness and ductility. This makes stainless steel widely used in manufacturing industries, including automotive, aerospace, construction and manufacturing.
Aesthetic: The surface of stainless steel is smooth and uniform, and it can show different appearance effects by polishing, brushing or painting. This makes stainless steel in architectural decoration, furniture manufacturing, art production and other fields have a wide range of applications.
Renewable: Stainless steel is a recyclable material, through recycling and reuse, can reduce resource consumption and environmental pollution, in line with the principle of sustainable development.
In general, stainless steel has excellent properties such as corrosion resistance, high temperature resistance, good mechanical properties, aesthetics and renewability, making it widely used in various industrial and civil fields.
Chemical Composition:
Stainless steel is an austenitic stainless steel that has a composition of chromium, nickel, and manganese. Its chemical composition is as follows:

We can provide different specifications and sizes of stainless steel, and can choose the appropriate thickness and width according to the specific needs.
Hot Rolled and Cold Rolled
Stainless steel products can be manufactured using either hot rolled or cold rolled techniques. Hot rolling involves heating the steel above its recrystallization temperature and then passing it through rollers to form the desired shape. Cold rolling, on the other hand, involves passing the steel through rollers at room temperature to reduce its thickness.
Corrosion Resistance:
★Resistance to moderately aggressive organic acids is a result of the 9 to 11% nickel that the 304 alloys contain.
★Resistance to corrosion in oxidizing environments is a result of the 18 to 19% chromium that the 304 alloys contain.
★The 304, 304L, and 304H may be considered to perform uniformly in most corrosive environments.
Heat Resistance:
★Continuous use of 304 in the 800-1580°F range is not recommended if subsequent aqueous corrosion resistance is
important.
Machinability:
★The use of chip breakers is advised since the chips can be stringy. Stainless steel work harden rapidly, heavy positive
feeds, sharp tooling, and a rigid set-up should be used.of cut below the work-hardened layer resulting from the previous
passes.
★Good oxidation resistance in intermittent service to 1600°F and in continuous service to 1690°F.
Different Finishes
Stainless steel comes in different finishes that can affect its appearance and properties. Here are some common finishes:
| Different Finishes |
| 2B: This is a smooth, reflective finish that is produced by cold rolling followed by annealing and descaling. |
| No.1: This is a rough, dull finish that is produced by hot rolling followed by annealing and pickling. |
| SB: This is a satin finish that is produced by applying a fine abrasive material to the surface of the steel. |
| BA: This is a bright, mirror-like finish that is produced by buffing the surface of the steel with a fine abrasive material. |
| HL: This is a hairline finish that is produced by brushing the surface of the steel with a fine abrasive material. |
| Mirror: This is a highly reflective finish that is produced by polishing the surface of the steel with a very fine abrasive material. |
