FAQ

Q: Why choose 304 stainless steel over 409 for exhaust parts?

A: 304 stainless steel contains higher nickel content (~10%), providing better corrosion resistance, weldability, and heat resistance than 409 grades.

Q: What is the maximum operating temperature for 304 stainless exhaust parts?

A: Up to 800°C continuously, making it suitable for high-performance turbocharged and racing applications.

Q: What surface treatment options are available?

A: We offer mirror polishing, sandblasting, electroplating, and passivation for improved aesthetics and corrosion protection.

Q: How long is the lead time for custom orders?

A: Standard lead time: 25-45 days (including mold production).

Q: Can you supply large-volume orders?

A: Yes, we support mass production with consistent quality control (ISO 9001 certified).

Q: Do your parts comply with international environmental regulations?

A: Absolutely. Our materials meet RoHS, REACH, and other global environmental standards.

Q: How does investment casting compare to machining in cost efficiency?

A: Precision casting reduces material waste and machining needs, lowering production costs while ensuring high dimensional accuracy.
