Stainless Steel Cold Rolled Coil 304 304L 321 Polished Color Stainless Steel Coil

Product of description

304 stainless steel coil:
Composition: The main composition of 304 stainless steel coil is 18% chromium (Cr) and 8% nickel (Ni), and also contains a small amount of carbon (C), manganese (Mn) and other elements.
Features: Good corrosion resistance, high temperature resistance and oxidation resistance. It has high strength and wear resistance and can be used in a wide temperature range. Has good weldability and processability.
Application: Widely used in food processing equipment, chemical containers, architectural decoration, pressure vessels and other fields.
304L stainless steel coil:
Composition: 304L stainless steel coil is a low-carbon version of 304 stainless steel, and its carbon content is lower, usually controlled below 0.03%.
Features: Compared with 304 stainless steel, 304L stainless steel coil has better resistance to intergranular corrosion, especially for welding parts. The corrosion resistance and high temperature resistance of 304 stainless steel coils are maintained.
Application: Commonly used in welding components, chemical equipment, food processing equipment, pharmaceutical equipment and other occasions that require high intergranular corrosion.
321 stainless steel coil:
Composition: Titanium (Ti) element is added to 321 stainless steel coil to stabilize its structure and resist carbonization and intergranular corrosion in high temperature environment.
Features: Good heat resistance and corrosion resistance, especially excellent mechanical properties at high temperatures. It has good weldability and machinability.
Application: Suitable for applications in high temperature environments such as high temperature heat exchangers, stoves, automobile exhaust systems, and chemical equipment.
It is necessary to select a suitable stainless steel coil according to the specific use requirements and engineering conditions. The above is a brief introduction to the characteristics and main application scenarios of three common stainless steel coils. In practical application, further evaluation and selection should be carried out according to specific material specifications, surface treatment and engineering requirements.
