Material Description
Corrax is a stainless steel developed for Additive Manufacturing, and is a corrosion resistant iron-based powder used in the DMLS process. Corrax is a tooling grade steel characterized having a good corrosion resistance combined with high strength and hardness. These properties make it perfectly suitable for tools for plastic molds including demanding applications such as molds for medical parts.
Material Properties
High strength and hardness Excellent mechanical properties
Easy to treat and machinable Can be highly polished
Applications
Corrax is intended for injection molding tools, molding of corrosive plastics, medical engineering & plasticizing tool parts and other industrial applications where high strength and hardness are required, and parts built from Corrax can be machined, shot-peened and polished in as-built or heat-treated status easily.
