304/304L Stainless Steel: It exhibits good corrosion resistance and finds wide applications in general purposes.
316/316L Stainless Steel: Performs exceptionally well in corrosive environments, making it particularly suitable for marine and chemical industries.
321 Stainless Steel: Possesses high-temperature resistance and is commonly used for elevated temperature applications.
310S Stainless Steel: Suitable for use in high-temperature and highly corrosive environments.
904L Stainless Steel: Used for extremely corrosive environments and high-temperature conditions, such as sulfuric acid and acidic conditions.
Applications
Stainless Steel Seamless Square Tubes are commonly made from various stainless steel grades, including 304/304L, 316/316L, 321, 310S, 904L, and others. Different stainless steel grades offer varying levels of corrosion resistance, high-temperature performance, and strength, allowing for appropriate material selection based on specific application needs.
The main advantages of Stainless Steel Seamless Square Tubes are similar to those of stainless steel seamless pipes, and they include:
Excellent Corrosion Resistance: Seamless square tubes have no welds or seams, reducing the possibility of corrosion and making them suitable for conveying corrosive media.
High Strength: Cold worked Stainless Steel Seamless Square Tubes exhibit high strength and pressure resistance.
Safety: The absence of welds in seamless square tubes provides better safety in high-pressure and high-temperature applications compared to welded tubes.
Smooth Surface: Seamless square tubes have smooth inner and outer surfaces, facilitating fluid transmission and reducing flow resistance and pressure loss.
