What is the maximum weight for heavy steel castings?

Neocast Alloys can manufacture heavy steel castings up to 500kg single piece weight using investment casting process. For even larger components, we can produce castings up to 1200mm maximum dimension with tolerances from CT5 to CT8 as per ISO 8062.

What types of heavy components can be cast?

We manufacture a wide range of heavy components including large flanges, gearbox housings, bearing blocks, pump and compressor bodies, machinery frames, mining and crusher parts, and marine/offshore components. All castings can be delivered fully machined and ready for assembly.

What materials are available for heavy steel castings?

Heavy castings are available in carbon steel (WCB, WCC, LCB), alloy steel (WC6, WC9, 4140, 4340), stainless steel (CF8, CF8M, CA6NM), duplex steel, manganese steel for wear resistance, and Ni-Hard grades for abrasion-resistant applications.
