Types of Stainless Steel Welded Micro Tubes
Stainless Steel 304 Micro Tubing / 304L Micro Tubing
SS 304 Micro Tube / 304L Micro Tube is the most widely used austenitic stainless steel, valued for its good general corrosion resistance, excellent formability, and reliable strength. The lower carbon content in the "L" grade enhances weldability, making it a versatile choice for general instrumentation, food and beverage components, automotive parts, and consumer electronics where moderate corrosion resistance is sufficient for SS micro tubes.
Small Diameter Stainless Steel 316 Tubing / 316L Micro Tubing
SS 316 Micro Tube / 316L Micro Tube is an austenitic stainless steel alloyed with molybdenum, delivering excellent corrosion resistance, especially against chlorides and acidic environments. The low carbon "L" grade (316L micro tube) offers improved weldability, making Stainless steel 316 micro tubing ideal for demanding applications such as medical devices, pharmaceutical processing, marine components, chemical lines, and analytical instrumentation requiring superior corrosion resistance in Small diameter stainless steel tubing.
