Additive Manufacturing 18 Ni Maraging Steel

Designed for Processing in Laser Powder Bed Fusion (PBF-LB) Systems Applications

MetcoAdd™ C300-A is an iron-nickel-cobalt based powder similar to 18 Ni ▪▪ Tools and dies maraging steel. The alloy chemistry is known to provide ultra high strength in ▪▪ Plastic injection molds combination with toughness and resistance to cracking. The composition of the ▪▪ Light metal and pressure die casting powder is similar to Werkstoff Nr. 1.2709 / X3NiCoMoTi 18-9-5 and AMS 6514. ▪▪ Cold extrusion tools Room temperature static properties of PBF-LB processed and heat treated material coupons have been shown to be comparable to those of AMS 6514. For reference purposes Oerlikon has processed MetcoAdd C300-A using fixed parameters and 40 μm layer thickness to provide data below. Additional testing has been performed by an extensive network of consortia and customer partners on a broader range of machine types. Properties may be optimized based on application specific requirements.
