ASTM A213/ASME SA213 T5 ALLOY STEEL SEAMLESS TUBE FOR HEAT EXCHANGER
Overview:
Grade T5 Seamless Tube is a type of alloy steel tube that is designed for use in high-temperature applications. The T5 grade of alloy steel contains a high concentration of chromium and molybdenum, which give it excellent resistance to high-temperature oxidation and corrosion.
The T5 Seamless Tubes are commonly used in industries such as power generation, chemical processing, and oil and gas production. They are also used in heat exchangers, boilers, and other high-temperature applications.
The T5 Seamless Tube is seamless, meaning that it has no welded joints. This makes it highly resistant to leaks and reduces the probability of failure in high-pressure applications. The tube is available in various sizes, and thicknesses, and can be produced according to client specifications with strict adherence to international standards such as ASTM A213 and A269.
The T5 Seamless Tube's high-temperature oxidation resistant properties are due to the high levels of chromium and molybdenum in addition to a small percentage of carbon. These chemical properties ensure that the tube has excellent corrosion resistance and can withstand high temperatures.
The tube's molybdenum content also gives it excellent mechanical properties, including high tensile strength, hardness, and wear resistance. This makes it ideal for use in applications requiring high strength and durability.
The T5 Seamless Tube can also be easily machined and fabricated into various shapes and sizes without compromising its structural integrity. It is also capable of being welded using standard welding procedures and without preheat treatments.
