Chemical Composition
304 Stainless Strip Coils contains approximately 18% chromium and 8% nickel, with a maximum carbon content of about 0.08%. The chromium content forms a passive chromium - oxide film on the surface, which provides excellent corrosion resistance. Nickel enhances the material's ductility and toughness.

Mechanical Properties
The tensile strength of 304 Stainless Strip Coils typically ranges from 515 MPa to 760 MPa. It has good yield strength, usually around 205 MPa - 210 MPa. The elongation at break can be around 40% - 60%, which means it has good ductility and can be formed into different shapes without cracking easily.

Surface Selection
Manufacturing Process
The production of 304 Stainless Steel Coil usually starts with melting the raw materials in an electric arc furnace. Then, through continuous casting, the molten metal is formed into slabs. These slabs are hot - rolled to reduce their thickness and then cold - rolled to achieve the final desired thickness and surface quality of the coil. After cold - rolling, annealing is often carried out to relieve internal stresses and improve the material's mechanical properties.
Applications
In the food and beverage industry, 304 Stainless Steel Coil is used to make food processing equipment, storage tanks, and conveyor belts due to its non - reactive and hygienic properties. In architecture, it is used for roofing, wall cladding, and handrails because of its aesthetic appeal and corrosion resistance. In the automotive and transportation sectors, it is used for exhaust systems and vehicle trim parts. It is also a popular choice for making household appliances such as refrigerators, dishwashers, and ovens due to its durability and resistance to stains and corrosion.
The new generation of high-strength automotive steel, oriented silicon steel, advanced steel for household appliances, energy and marine engineering steel, bridge steel, hot-rolled heavy rail and other high-end products independently developed have all reached the world's advanced level.
