Frequently Asked Questions
What is the difference between 304 and 316L stainless steel tubes?
316L contains molybdenum (Mo) for better resistance to saltwater and acids; 304 is more economical for general water pipelines and architecture.
Seamless vs. welded stainless steel tube - Which is better?
Seamless is ideal for higher pressure and precision applications, while welded is cost-effective for general industrial and commercial use.
Are stainless steel tubes magnetic?
304 and 316L are typically non-magnetic; however, ferritic grades like 430 or duplex grades like 2205 can be magnetic.
Can I use stainless steel tubes for drinking water?
Yes, 304/316L tubes comply with FDA/NSF standards, are non-toxic, and are safe for drinking water transport.
Do you offer custom sizes and finishes?
Yes, we provide customization for outer diameter (6mm-1200mm), wall thickness (0.3mm-20mm), length, and various finishes including 2B, BA, and mirror polish.
How is quality assured?
We offer full traceability via Mill Test Reports (MTR) and support third-party inspections by SGS or BV.
