FAQ

Q: What is the difference between High Carbon Silicon 68# and 65#?

A: High Carbon Silicon 68# contains 68% minimum silicon, providing higher silicon addition efficiency than 65# while maintaining high carbon content for metallurgical applications.

Q: 2. How do I choose the correct particle size?

A: 1–10 mm for precise alloy addition.
10–50 mm for general steelmaking.
50–100 mm for large electric arc or induction furnaces.

Particle size selection depends on the furnace type and feeding system.

Q: Can I request a sample before placing a bulk order?

A: Yes. Sample orders are available. Customers typically pay the sample cost and courier freight, which can be discussed based on project requirements.

Q: Which payment methods do you accept?

A: We normally accept T/T for bulk orders. Western Union and PayPal are available for sample fees and courier charges.

Q: Do you provide export documents?

A: Yes. We can provide commercial invoice, packing list, certificate of origin, bill of lading, and other export documents required by the destination country.

Q: How should High Carbon Silicon 68# be stored?

A: Store the product in a dry, well-ventilated warehouse away from moisture and contaminants. Keep the packaging sealed until use to maintain product quality.

Q: What after-sales support do you provide?

A: We provide technical specification confirmation, production tracking, pre-shipment inspection support, export documentation assistance, and responsive after-sales communication for every order.
