Stainless steel capillary tubes are available in a wide range of sizes and wall thicknesses and can be customised to suit different application requirements and design specifications. Stainless steel capillary tube commonly used materials are austenitic 300 series, duplex steel, nickel alloy, etc. 3

Stainless steel is a type of steel that is resistant to weak corrosive substances like air, steam, and water. It is also resistant to chemical substances like acids, alkalis, and salts. This type of steel is commonly known as stainless steel. On the other hand, there is another type of steel that is resistant to chemical substances but not necessarily to weak corrosive substances. This type of steel is called acid-resistant steel. The corrosion resistance of stainless steel depends on the specific alloying elements present in the steel.

Nickel alloys were created in the late 1930s. In 1941, Britain produced the first nickel-based alloy called Nimonic 75 (Ni-20Cr-0.4Ti), and later improved it by adding Al to enhance its creep strength, resulting in Nimonic 80 (Ni-20Cr-2.5Ti-1.3Al). The United States, Russia, and China also developed their own nickel-based alloys
