Analysis of Processing Properties of 304 Thick-Walled Stainless Steel
The 304 stainless steel family, derived from the 304 grade, is well-known for its excellent surface finish characteristics. A wide range of surface treatments available in the market today are compatible with 304 series stainless steel, making it a popular choice across various industries.
First, one of the most common surface finishes is dry sanding and wire drawing, which includes filament and short wire patterns. After this treatment, 304 stainless steel achieves a visually appealing appearance that meets the requirements of general decorative applications. Typically, a single pass of brushing can produce a satisfactory result, making it ideal for cost-effective and efficient production.
Due to the low cost of the equipment, ease of operation, and minimal processing expenses, these methods have become essential tools in machining centers. As a result, most machining centers offer sanding plates with filament and short wire finishes, with 304 stainless steel being used in over 80% of such applications.
Second, another popular technique is oil-milled wire drawing. After oil grinding, 304 stainless steel exhibits a refined and elegant finish, often used in elevator panels, home appliances, and other decorative surfaces. Cold-rolled 304 stainless steel usually achieves good results after a single sanding pass. Some modern machining centers now also offer oil-based frosting for hot-rolled stainless steel, delivering an effect that closely resembles that of cold-rolled oil-milled surfaces. This advancement has expanded the versatility and application range of 304 stainless steel in both industrial and aesthetic contexts.
