We supply a wide range of materials including Carbon Steel, Chrome Steel (AISI 52100), Stainless Steel (304, 316, 420, 440C), Aluminum, Copper, and Brass.
If the items are in stock, delivery takes 2-5 days. For custom production or large quantities, it typically takes 20-35 days depending on the specifications.
Standard packaging is 20-25kg per carton, and 1 ton per wooden pallet. We also offer steel drums or specific plastic bag requirements based on customer needs.
Our chrome steel balls range from G10 to G1000, ensuring high precision for various industrial and bearing applications.
We support Express (for small/urgent orders), Air Freight, and Sea Freight for bulk shipments to ensure cost-effectiveness.
Chrome steel balls offer fair corrosion resistance in fresh water and organic materials, but for high corrosion environments, we recommend our Stainless Steel series.
