Quality StandardsFrequently Asked Questions
What's the difference between 304 and 316 stainless steel?
316 contains molybdenum, providing superior corrosion resistance in chloride environments. 304 is suitable for general applications, while 316 is preferred for marine and chemical environments.
Can stainless steel be electropolished?
Yes, we offer electropolishing services to achieve mirror-like finishes and improve corrosion resistance. Electropolishing also removes surface contaminants.
What's your capability for tight tolerances on stainless steel?
We can achieve ±0.01mm tolerances on stainless steel parts using precision CNC machines and CMM verification.
Can you machine POM (Acetal) plastic?
Yes, we have extensive experience machining POM and other engineering plastics with excellent surface finishes and dimensional accuracy.
What's the lead time for stainless steel parts?
Typically 2-4 weeks for standard orders, with expedited services available for urgent requirements.
Are your stainless steel parts biocompatible?
Yes, we can provide biocompatible stainless steel parts with appropriate material selection, processing, and certification for medical applications.
Can you provide passivation documentation?
Yes, we provide passivation test reports and documentation per ASTM A967 and other applicable standards.
What's your experience with medical-grade applications?
We are ISO 13485 certified and have 10+ years of experience manufacturing medical-grade components with full traceability and documentation.
