Steel casting facing sand Chromite sand AFS40-45

Steel casting facing sand Chromite sand AFS40-45 is a foundry-grade chromite sand. With a high Cr2O3 content of more than 46% and SiO2 of less than 1%, the chromite sand works excellent as core sand, molding sand, shape sand, and facing sand for casting. The chromite sand from Haixu Abrasives gets high thermal and chill performance after water washing and magnetic removal in our factory in China. The low Silica and mud impurities make sure the chromite sand can improve sand sticking. It can improve the surface quality of casting. Chromite sand is particularly suitable for large steel & iron castings. The excellent thermal conductivity can transfer the heat out quickly. Thus it can avoid porous in the castings.

FAQ:

Q: Where are you located?

A: Our factory is located in a tariff-free Zone at Lianyungang port. So it will be convenient to export.

Q: What is your main market?

A: Our main market is local China and Asia-Pacific regions.

Q: What is the difference between your chromite sand and Original South Africa Chromite sand?

A: In our factory, we take production processes on original South Africa such as washing, magnetic removing, and sieving. So it is cleaner with fewer impurities, and less magnetic content. The cleanness of chromite from us is just proper for the foundry industry. In the meantime, we will get a precise AFS size and make customized particle size distribution to the requirement.

Q: What is the MOQ?

A: No. We don’t have a limit on MOQ, but for a small quantity, the transportation cost would be high.

Q: Can you provide free samples?

A: Yes, free samples within 25 kgs are available. You only have to bear the express cost.

Q: What is the delivery time for one container?

A: What is your capacity each year?

Q: Our capacity per year is 2500-3000 tons.

A: Generally the lead time of FCL is 7-10 days. A bigger quantity will get a longer delivery time.

Q: What is the HS code of Chromite sand?

A: The chromite sand HS code is 2610000000.

Q: Do you get MSDS of chromite sand?

A: Yes. You can download it from our website or get it from our sales team.
