Iron steel casting sand Chromium ore 50-100 mesh
Product Introduction of Iron steel casting sand Chromium ore 50-100 mesh
Iron steel casting sand Chromium ore 50-100 mesh is a kind of foundry sand with high refractoriness. The content of chromium oxide in casting chromite sand should be at least 46%. That will get a high Solid-phase sintering temperature. Chrome ore sand is especially featured with its high thermal conductivity. It can not only make the casting steel cool quickly but also prevent casting iron& steel from sand-sticking.

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.
