Abstract
Low-alloy cast steels are used in many branches of industry for various mechanical parts with very different wall thicknesses (40-400mm). The mechanical properties in such sections must be equal throughout. For these reasons, there are several grades of cast steels, which fulfil the requirements for different uses. This chapter characterises the parameters of low-alloy cast steels, intended for several service conditions.
