Atomfair CX (Corrax) Stainless Steel Powder
CX (Corrax) is a low-carbon precipitation-hardening stainless steel. It gains strength through precipitating B-NiAl intermetallic phases and ordered CsCl structure, with excellent corrosion resistance. Suitable for SLM, it’s used in injection molds, extrusion molds and engineering components.
