FAQ
What makes Feige Steel Ball’s products suitable for high hardness applications?
Our manufacturing process incorporates specialized heat treatment techniques that achieve optimal hardness levels (HRC58-65) while maintaining material integrity. The GCr15 bearing steel we use contains 1% carbon and 1.5% chromium, creating a martensitic structure that provides exceptional wear resistance without becoming brittle. Each batch undergoes rigorous hardness testing using Rockwell scales to ensure consistency.
How does the company ensure dimensional precision in micro steel balls?
We employ advanced grinding and lapping equipment capable of maintaining tolerances as tight as ±0.001mm for diameters below 1mm. Our quality control system implements three-stage inspection processes using high-precision measuring instruments, including laser micrometers and optical comparators. Statistical process control (SPC) methods monitor production parameters in real-time to prevent dimensional deviations.
What surface treatments are available for enhanced wear resistance?
In addition to standard heat treatment, we offer specialized surface coatings including: 1) Chrome plating for additional hardness and corrosion protection; 2) Black oxide coating for reduced friction and improved lubricant retention; 3) Passivation treatment for stainless steel balls to enhance corrosion resistance; 4) Custom polymer coatings for specific chemical environments. Each treatment undergoes adhesion and durability testing before approval.
How does Feige handle non-standard shape requirements?
Our CNC machining centers can produce custom shapes including truncated cones, elliptical balls, and asymmetrical forms with precision up to ±0.01mm. The process begins with 3D modeling and simulation to validate design feasibility, followed by prototype production and testing. We maintain detailed documentation of all custom orders to ensure consistent reproduction for future requirements.
What warranty terms apply to exported products?
All exported steel balls come with a 12-month quality warranty covering material defects and manufacturing flaws. We offer free replacement for any products failing to meet specified hardness or dimensional requirements within this period. Additionally, our lifetime technical support service provides assistance with application-specific selection and troubleshooting, even beyond the warranty period.
