EN 10293 GE300 / GS‑60 (1.0558) – Material Specification & Sand Casting Production
Material Overview
EN 10293 GE300, historically known as GS‑60 (1.0558), is a widely used carbon steel casting material defined by the European standard EN 10293 (Steel Castings for General Engineering Uses). It replaces the older German standard DIN 1681:1985 and delivers reliable mechanical performance for structural components in general engineering.
