Ferritic stainless steel is another type used in the manufacturing of oval tubes. It possesses lower levels of nickel compared to austenitic stainless steels but contains higher amounts of chromium (16-18%). A common example within this category is grade 430.
Grade 430 exhibits good corrosion resistance but may be more prone to oxidation compared to austenitic grades when exposed to high temperatures or certain corrosive environments. However, it offers excellent resistance to nitric acid and other non-oxidizing acids, making it suitable for specific applications in the chemical industry.
Duplex stainless steel is a unique grade that combines the properties of both austenitic and ferritic stainless steels. It offers an excellent balance of corrosion resistance and strength, making it ideal for demanding applications. One commonly used duplex grade is S31803 (also known as 2205).
S31803 exhibits enhanced resistance to pitting and crevice corrosion, making it suitable for use in aggressive environments such as marine or offshore applications. Its high strength provides structural integrity, allowing for thinner tube walls while maintaining performance requirements.
The surface finish of stainless steel oval tubes not only affects their aesthetic appeal but also plays a significant role in their performance and functionality. Three popular surface finishes used are polished finish, brushed finish, and satin finish.
A polished finish is achieved by buffing the tube's surface using fine abrasives until a smooth and reflective appearance is attained. This finish enhances the tube's visual appeal and provides optimal corrosion resistance by creating a barrier against environmental elements. It is commonly used in architectural applications where aesthetics are crucial.
A brushed finish involves creating parallel lines on the tube's surface using abrasive materials or mechanical brushing techniques. This finish imparts a distinctive texture that not only adds visual interest but also helps mask scratches or signs of wear over time. The brushed finish is widely utilized in both indoor and outdoor settings due to its durability.
The satin finish offers a subdued luster with a silky-smooth texture achieved by removing any visible polishing marks from the tube's surface. This finish strikes a balance between the high reflectivity of a polished finish and the matte appearance of a brushed finish.
Satin-finished oval tubes are often chosen for applications where both aesthetics and functionality matter, such as furniture manufacturing or decorative elements in architecture. Stainless steel oval tubes come in various grades, each catering to specific requirements.
Austenitic stainless steel, including grades 304 and 316, provides excellent corrosion resistance and formability, making them ideal for architectural applications.
