304 and 316 stainless steel are both austenitic grades, but 316 contains molybdenum, which gives it better corrosion resistance, especially in chloride environments. 304 is more commonly used and less expensive, making it suitable for many applications, while 316 is preferred for more demanding corrosive conditions.
304 capillary tubes in China are typically manufactured through a cold drawing process. The stainless steel is drawn through progressively smaller dies to achieve the desired diameter and wall thickness. This is followed by heat treatment, surface finishing, and rigorous quality control to ensure the tubes meet precise specifications.
The industries in China that use 304 capillary tubes most extensively include medical and pharmaceutical, aerospace and defense, automotive, chemical processing, food and beverage, and electronics manufacturing. These sectors rely on the precision, corrosion resistance, and versatility of 304 capillary tubes for various applications.
Yes, 304 stainless steel capillary tubes can be used in high-temperature applications. They maintain their strength and corrosion resistance at temperatures up to 870°C (1600°F). However, for prolonged exposure to very high temperatures, specialized high-temperature alloys may be more suitable.
304 capillary tubes produced in China typically have outer diameters ranging from 0.3 mm to 25 mm and wall thicknesses between 0.1 mm and 6 mm. However, manufacturers can produce custom sizes to meet specific application requirements, with some capable of producing tubes with even smaller dimensions for specialized uses.
