FAQ
Q: What is the minimum order quantity for custom sizes?
A: Stock sizes start from 100 kg. Custom dimensions require 500 kg minimum, with production lead time of 25-40 days.
Q: Can you provide material certificates?
A: Yes, we provide EN 10204 3.1 certificates with complete chemical composition and mechanical property test results for each batch.
Q: How do titanium bolts compare to stainless steel in corrosion resistance?
A: Titanium forms a stable passive oxide layer providing superior resistance to chloride pitting and stress corrosion compared to 316 stainless steel.
Q: Are your bolts suitable for cryogenic applications?
A: Absolutely. Titanium alloy maintains ductility and toughness at temperatures down to -200°C without brittleness concerns.
Q: What surface treatment do you recommend for marine environments?
A: Plain (uncoated) titanium offers best corrosion resistance. The natural oxide film self-heals and requires no additional coating.
Q: Can you manufacture bolts with drilled heads for safety wire?
A: Yes, we offer CNC-drilled holes through hex head flats, typically 1.6-2.0mm diameter per customer specifications.
