Frequently Asked Questions (FAQs)
Q: What's the difference between SUS304 and SUS316 for boiler tubes?
A: SUS316 contains 2-3% Mo for superior chloride resistance, ideal for marine/chemical environments. SUS304 is cost-effective for general high-temperature uses.
Q: Can you supply JIS G3463 tubes with NDE testing?
A: Yes! We offer 100% hydrostatic testing, UT (ultrasonic), and Eddy Current inspection.
Q: What's the lead time for custom sizes?
A: 15-30 days for seamless tubes (depending on quantity).
