Frequently Asked Questions
A: The main difference is in their chemical composition. 316 stainless steel contains molybdenum (2-3%), which enhances its corrosion resistance, particularly in chloride environments. 304 is more suitable for general industrial applications where extreme corrosion resistance isn't required.
A: We can supply capillary tubes up to 6 meters in length as standard. For longer lengths or special requirements, please contact our sales team for custom solutions.
A: Yes, we can provide samples for your evaluation. Please contact our sales department to arrange sample orders and discuss any specific testing requirements you may have.
A: For custom sizes or special requirements, the lead time may be 15-30 working days depending on the complexity of the order. Our sales team will provide you with an accurate estimate based on your specific requirements.
