High - Quality SUS630/17 - 7PH Duplex Stainless Steel Tube at a Competitive Price
Product Overview
Our SUS630/17 - 7PH duplex stainless steel tube is a remarkable product that combines excellent mechanical properties with high corrosion resistance. This tube is crafted to meet the diverse needs of various industries, from aerospace to chemical processing. The unique composition of SUS630/17 - 7PH stainless steel makes it stand out in the market, offering a perfect balance between strength and durability.
Material and Surface Treatment
The tube is made from SUS630/17 - 7PH duplex stainless steel, which is a precipitation - hardening stainless steel. It contains a precise blend of elements such as chromium, nickel, and copper, which contribute to its outstanding performance. The surface of the tube undergoes a polished treatment. This polished finish not only gives the tube an aesthetically pleasing appearance but also enhances its corrosion resistance. The smooth surface reduces the adhesion of contaminants, making it easier to clean and maintain, which is crucial in applications where hygiene is a priority.
Manufacturing Technique
We use the hot - rolled technique to manufacture these tubes. Hot rolling is a well - established process that involves heating the steel above its recrystallization temperature and then passing it through rollers to achieve the desired shape and dimensions. This technique results in a tube with a fine - grained microstructure, which improves its mechanical properties such as strength and toughness. The hot - rolled tubes have better ductility, allowing them to be easily formed and fabricated into different shapes according to the specific requirements of our customers.
Shape and Standard
The tube has a round shape, which is one of the most common and versatile shapes in the industry. The round shape provides uniform stress distribution, making it suitable for applications where pressure or fluid flow is involved. Our tubes are manufactured to meet the ASTM standard. Adhering to the ASTM standard ensures that the tubes have consistent quality, reliable performance, and are compatible with international specifications. This makes our tubes a preferred choice for customers around the world who require high - quality and compliant products.
Applications
Aerospace Industry: The high strength - to - weight ratio and excellent corrosion resistance of SUS630/17 - 7PH duplex stainless steel tubes make them ideal for aerospace applications. They can be used in aircraft structural components, landing gear parts, and engine components, where reliability and performance under extreme conditions are essential.
Chemical Processing: In the chemical industry, these tubes can withstand the corrosive effects of various chemicals. They are used in pipelines, reactors, and storage tanks, ensuring the safe and efficient transportation and storage of chemicals.
Medical Equipment: The polished surface and corrosion resistance of the tubes make them suitable for medical applications. They can be used in the manufacturing of surgical instruments, medical implants, and equipment for medical facilities, where cleanliness and biocompatibility are crucial.
Automotive Industry: For automotive applications, these tubes can be used in exhaust systems, fuel lines, and suspension components. Their strength and durability help improve the performance and longevity of vehicles.
