Product Q&A

Q:Are you a manufacturer or trading company?

Direct manufacturer - 6,000 sqm, 17 years, 40+ CNC machines, ISO9001, 3D CMM.

Q:What is 17-4PH stainless steel?

Martensitic precipitation-hardening stainless steel offering high strength (up to 1,310 MPa), hardness, and corrosion resistance.

Q:What is black oxide coating?

Chemical conversion coating forming black magnetite (Fe3O4) finish on stainless steel. Provides anti-glare satin black appearance, corrosion resistance, and meets MIL-DTL-13924 Class 4 standards.

Q:Does black oxide add thickness to parts?

No - coating is approximately 1 micron (0.000020 inches) thick and adds no measurable thickness, ideal for tight-tolerance components.

Q:What are the benefits of black oxide for engine mounts?

Anti-glare finish, corrosion resistance (when sealed), uniform appearance, dimensional stability, and military specification compliance.
