Continuous-cast products from GP are of outstanding quality. We can deliver this very high level of quality because we have consistently enhanced our processes in decades of experience in continuous casting. In series production, we use computer-based expert systems that permanently monitor and efficiently control our processes. Our continuous-cast products possess a very dense and fine-grained microstructure that can be further refined by dedicated heat treatments to achieve superior homogeneity and further improved isotropic properties in the material. This results in excellent mechanical design parameters that guarantee reliable in-service performance of the components and make high precision, close-tolerance machining at high speeds possible. Thus, machining costs can be saved in addition to the economic benefit provided by the continuous casting process. We supply a broad range of standard sizes and grades from stock, in addition to customized dimensions and special grades, in as-cast, pre- and finish-machined and any other treatment condition.
