18Ni300 Metal PowDer PrecisionEngineering SLM Material

2. **Material process solution**
- SLM printing parameter recommendation for 18Ni300
- Heat treatment guideline: solid solution + aging process,dimensional control scheme
- Post-processing technical support: CNC machining, EDM, shotpeening and nitriding treatment
- Defect prevention strategy to reduce porosity, crack risk andresidual stress for aero-engine load-bearing parts
What Rite Material does NOT replace
It is important to understand the boundaries:
? Printing parameter development (EOS / BLT / Renishaw materialcards, laser parameter tuning)
? Part topology optimization and support-structure design
? Aerospace certification (AMS, NADCAP, customer P)
? Fatigue / fracture-toughness database generation
They solve problems related to powder inconsistency, printingdefects (porosity, balling, poor layering), low strength due tohigh oxygen, and unclear heat-treatment procedures.瑞拓美新材料

> Limitation reminder:
> Performance degradation occurs under continuous servicetemperature above 400°C. Therefore, 18Ni300 components arerestricted to cold zones of aero engines and cannot be applied tohot-end parts such as turbine blades, combustors and turbinedisks.
Here is the English version of the previous introduction, polishedfor a professional tone:
Rite Material (Changsha Ruituomei New Materials Co., Ltd.)? is aChinese metal powder supplier specializing in additivemanufacturing feedstock, brazing alloys, and specialty metalpowders (iron, copper, silver, nickel, and titanium-based). Theirproduct portfolio includes LPBF-grade 18Ni300 (Maraging 300 /1.2709), CuSn, AgCuTi, CuCrZr, and other gas-atomized powders.
 
- SLM prints lightweight, organic topology optimized structures byconsolidating multiple welded sub-parts into one monolithiccomponent.
- 18Ni300 features ultra-high strength, good fracture toughness andnearly zero distortion after aging heat treatment, which canmaintain strict dimensional tolerance under long-term cyclicvibration.
- Shot peening post-treatment further improves fatigue resistanceto oid crack initiation under engine vibration.瑞拓美新材料
