Aerospace Precision Components: Used in the manufacture of aircraft control instruments, fuselage frames, and engine parts. Its high strength and fatigue resistance meet the extreme material requirements for flight safety.
High-End Medical Devices: Suitable for additive manufacturing of surgical instruments, implants, and other products. The material combines good biocompatibility, corrosion resistance, and necessary mechanical properties.
Industrial Springs and Fasteners: Used in the manufacture of precision springs, high-stress bolts, and other elastic elements operating in corrosive environments, ensuring long-term dimensional stability and reliability. Precision Molds and Parts: Complex molds, gears, etc., are manufactured using powder metallurgy or 3D printing technology. Their superior overall performance significantly improves the durability and precision of the parts.
Q1: How do I choose the powder particle size for my equipment?
A1: Common metal 3D printing equipment typically uses 15-53 micrometer or 20-63 micrometer particle sizes. Please provide your equipment model and process goals, and we will recommend the most suitable particle size distribution.
Q2: Do parts made using 17-7PH stainless steel spherical powder necessarily require heat treatment?
A2: Yes. To achieve the high strength designed for the material, the molded parts must undergo specific solution treatment, conditioning, and aging heat treatments to complete the microstructure transformation and precipitation strengthening.
Q3: How does the powder packaging prevent oxidation?
A3: We use double-layer vacuum packaging, with an outer moisture-proof aluminum foil bag to ensure the stability of the powder during storage and transportation.
Q4: What are the main differences compared to 17-4PH stainless steel spherical powder?
A4: 17-7PH is a semi-austenitic powder, exhibiting greater toughness in the solution-treated state and ease of forming and processing. High strength is subsequently achieved through complex heat treatment. 17-4PH stainless steel spherical powder is martensitic, with a relatively simpler processing method. Both are suitable for different performance and process requirements.
