G-X300CrMoNi15-2-1 (0.9640) chemical composition
Nickel-bearing variant of the 15% Cr-Mo white iron: the combined Mo and Ni additions raise hardenability, so heavier sections harden through after the destabilising heat treatment. Used for thick mill liners, grinding plates and pump wear parts.

We cast G-X300CrMoNi15-2-1
We sand cast high-chromium white iron wear parts for quarry and cement service, with GX300CrMo15-3 as our standard mill grade and further grades from 15 % to 27 % Cr, heat treat them in-house and machine them on CNC equipment in the group's own machine shop. Every melt is checked by spectrometer analysis, hardness is verified on our own tester, and EN 10204 3.1 certificates are available.
- Sand casting at our foundry in Mandra, Attica; centrifugal casting for bushings, sleeves and liners
- Heat treatment at the foundry (water, oil or air quench); CNC machining in our machine shop in Perama
- Spectrometer analysis of every heat, mechanical testing and NDT
- EN 10204 3.1 inspection certificates; ISO 9001 (both plants) and ISO 14001 (foundry) certified
