310S VS 309S stainless steel tubing for high temperature application
310S stainless steel is austenitic chromium-nickel stainless steel, which has good oxidation resistance and corrosion resistance. The high percentage of chromium and nickel content makes it have good creep strength, can work continuously at high temperatures, has good high-temperature resistance. High Ni, Cr (Cr) content makes it has good oxidation resistance, corrosion resistance, acid and alkali resistance, high-temperature resistance, used in the manufacture of electric furnace tubes, and other occasions. The strength of austenitic stainless steel increases with the increase of carbon content due to its solution strengthening effect. The austenitic stainless steel has high strength and creeps strength at high temperatures due to its face-centered cubic structure, which is based on chromium and nickel.
Excellent corrosion resistance and strength make Stainless Steel 309S Pipes ideal for parts that must withstand working temperatures of 1000°C. It is also known as high alloy stainless steel and is used extensively in exhaust machines, heat treatment furnaces, and heat exchangers, among other things, because of its exceptional high-temperature acid resistance and high-temperature strength. In high-temperature applications, austenitic stainless steels 309S and 310S are frequently utilised. They are slightly stronger at room temperature than austenitic 304 alloys and have better corrosion and oxidation resistance because to their high chromium and nickel content.
The temperature at which they are applied makes a difference:
The maximum operating temperature for the 310S is 1200°C, and the continuous use temperature is 1150°C. It is the most popular steel in the heat-resistant steel line.
Temperature range for the 309S: 900–1000°C. The highest working temperature is 1050°C, and at 650–700°C, a considerable load can be applied for extended periods of time.
Since 310S stainless steel pipe has a high torsional strength compared to its weight and is used for a variety of fluid pipelines, including those for oil, natural gas, water, gas, steam, and bending, it is also frequently used to make mechanical parts, engineering structures, conventional weapons, barrels, and shells.
Finally, the main distinction between 309S and 310S stainless steel is the amount of Ni and Cr present in each, which makes them resistant to fatigue, stress, and corrosion, which are common causes of tube failure with other materials. This is why applications requiring high-temperature performance call for the usage of 309S and 310S SS seamless tubes. Therefore, it is usually preferable to get stainless steel tubes from stainless steel manufacturers who provide quality items at fair costs if you’re looking for the best high-quality stainless steel tubes.
