IN718 powder is a high-performance nickel-based superalloy material. Leveraging its exceptional comprehensive properties, it plays a critical role across multiple high-end industrial sectors.
In the aerospace field, IN718 powder is extensively used in manufacturing hot-end components of aeroengines, such as turbine blades, combustion chambers, and turbine discs. It maintains stable mechanical performance even under high-temperature and high-pressure conditions. Within the energy industry, IN718 powder serves as an ideal choice for gas turbine components and nuclear reactor parts. In the oil and gas sector, its outstanding corrosion resistance makes it the preferred material for key equipment like downhole tools and valve systems.
IN718 nickel-based superalloy powder has achieved widespread application due to the following material characteristics:
(1) Outstanding Mechanical Properties: It maintains the highest yield strength among superalloys at temperatures up to 650°C and exhibits excellent creep and fatigue resistance.
(2) Excellent Corrosion Resistance: Possessing superior corrosion and oxidation resistance, it effectively withstands corrosion from chlorides, sulfides, and various acidic or alkaline media. Additionally, it forms a dense chromium oxide protective layer on high-temperature surfaces.
(3) Good Process Adaptability: It is suitable not only for traditional processes such as thermal spraying and powder metallurgy but also widely used in additive manufacturing and near-net-shaping technologies, including selective laser melting (SLM), laser-directed energy deposition (LDED), and hot isostatic pressing (HIP).
As a domestic provider of high-performance metal powder material solutions, Guangzhou Sailong Additive Manufacturing Co., Ltd. specializes in plasma rotating electrode atomization (PREP) technology. The IN718 nickel-based superalloy powder produced through this method features high sphericity, low oxygen content, strong flowability, and a low hollow powder rate. These properties ensure uniform powder spreading and melting stability during the 3D printing process, effectively reducing defects in printed parts and providing quality assurance for manufacturing dense components with excellent high-temperature mechanical properties and corrosion resistance.
Guangzhou Sailong has introduced a full-industry-chain service model encompassing "powder preparation, part manufacturing, and post-processing." Operating under the SGS-certified ISO9001 quality management system, the company is committed to providing global customers with professional full-chain additive manufacturing solutions. It continues to promote the innovative application of IN718 nickel-based superalloy powder in high-end fields such as aerospace and energy equipment.
