Maraging – EMETAL3D

Maraging Steel

Overview

MS1 Maraging steel also known as 18% Ni Maraging 300, European 1.2709 and German X3NiCoMoTi 18-9-5 is a is a type of high strength steel with superior strength and toughness without losing ductility. The materials require Aging that refers to the extended heat treatment process. These steels are a special class of low-carbon ultra-high-strength steels that derive their strength not from carbon, but from precipitation of intermetallic compounds. The parameter set offering and capability of Eplus3D for MS1 performance is included in this document.

Brief introduction

MS1 Maraging steel with the main alloy element Ni, Co, and Mo are added to produce intermetallic precipitates. Maraging steels are commonly used for tools and molds and are characterized by high hardness by simultaneously high ductility. The mechanical characteristics allow the use in highly stressed components because of the good wear resistance, due to that wear and tear is minimized. Maraging Steel MS1 is a steel powder which has been optimized, especially for processing in MPBF systems.

Heat treatment

To obtain good mechanical properties like ductility; strength and hardness up to 54HRC, the products need to be thermal post-hardened by age-hardening it at around 490 °C (914 °F) for minimum 6 hours. The steel is first annealed at approximately 820 °C (ca. 1,508 °F °F) for 15–30 minutes for thin sections and for 1 hour per 25 mm thickness for heavy sections, to ensure formation of a fully austenitized structure. This is followed by air cooling or quenching to room temperature to form a soft, heavily dislocated iron-nickel lath (untwined) martensite.

Recommendations are for guidance only and the suitability of the material for any application can only be confirmed upon getting to know the actual service conditions. Continuous development may cause changes in technical data without any prior notice. The current datasheet is only valid for EPlus3D materials.
All test data has been created with a well-maintained machine with well-maintained powder if machine is operated incorrectly or the feed material is not maintained performance of the material may not be seen.
Alterations to the parameter sets after they have been provided to the customer may also affect the overall performance of the material.
All tensile testing carried out to (DIN EN ISO 6892-1: 2020-06: A224, DIN 50125:2022-08: B6x30). Orientation Z defined as vertical perpendicular to the build plate. XY orientation defined as Parallel to the plate in the X or Y direction of the top view of the plate.
All Hardness measurements carried out to standard (ISO 6508-1:2016).
