Product Q&A

Q:Are you a manufacturer or trading company?

We are a direct manufacturer - 2,000 sqm, 17 years of experience, 30+ CNC machines, ISO9001, 3D CMM. Send inquiry for a live video tour of our shop floor.

Q:What is 316 stainless steel?

316 (UNS S31600) is an austenitic stainless steel with 16-18% chromium, 10-14% nickel, and 2.0-3.0% molybdenum, offering superior corrosion resistance, especially against chlorides and marine environments.

Q:Why is 316 preferred over 304 for fasteners?

316 contains 2.0-3.0% molybdenum, providing superior resistance to pitting and crevice corrosion in chloride environments - essential for marine, chemical, and outdoor applications.

Q:What is the tensile strength of 316 stainless steel fasteners?

316 stainless steel fasteners have a tensile strength of 85,000 psi.

Q:What precision tolerances can you achieve?

We routinely hold tolerances within +/-0.003mm (0.00012 inch) on critical features.
