FAQ
What makes your corrosion-resistant steel balls suitable for marine applications?
Our marine-grade steel balls use 316L stainless steel with enhanced molybdenum content for superior resistance to pitting and crevice corrosion in saltwater environments. Combined with specialized surface treatments like electropolishing or PVD coating, our products maintain performance even in harsh offshore conditions.
How do you ensure consistent quality across large production batches?
We implement a multi-stage quality control system with statistical process control (SPC) at each manufacturing stage. Key measures include: 1) Incoming material inspection, 2) In-process checks during cold heading and grinding, 3) 100% dimensional inspection using laser micrometers, and 4) Random sampling for destructive testing.
What is your minimum order quantity for custom specifications?
Our MOQ varies based on complexity but typically starts at 5,000 pieces for standard customizations and 10,000 pieces for fully customized solutions. We maintain flexible production scheduling to accommodate both large-volume orders and smaller prototype batches for new product development.
How do you handle urgent orders requiring expedited production?
We maintain dedicated production lines for priority orders and can often accommodate rush requests within 7-10 days for standard products. Our inventory management system keeps common specifications in stock for immediate shipment, while custom orders benefit from our streamlined production workflow.
What warranty do you provide on your corrosion-resistant products?
All our products come with a 12-month warranty against manufacturing defects. For corrosion-related issues, we offer extended warranty coverage up to 36 months when using our recommended surface treatments and maintenance procedures. Our technical team provides lifetime support for all products we supply.
