Raw Materials of Stainless Steel Furniture

Raw materials commonly used for stainless steel furniture are 304 stainless steel, and its key characteristics are as follows:

Material Properties

304 stainless steel contains over 18% chromium and 8% nickel, giving it excellent corrosion resistance. In harsh environments like acid rain and salt spray, a dense chromium oxide protective film naturally forms on its surface, effectively isolating it from corrosive agents.

Manufacturing Process

• Cold Rolling: Precisely controlled pressure and temperature ensure there are no stress concentration points when bending the steel.

• TIG Welding (Tungsten Inert Gas Welding): Welding is performed under a protective inert gas to prevent oxidation.

• Surface Treatment: Matte sandblasting is used to create a softer visual appearance, while mirror polishing enhances the self-cleaning ability of the surface.

Applications

It is widely used in coastal areas, industrial zones, and for outdoor furniture (such as metal planters) due to its resistance to harsh conditions like acid rain and salt spray.
