Description of 17-4 ph stainless steel Spherical Powder
17-4 PH stainless steel, also known as Type 630, is a precipitation-hardening martensitic stainless steel that offers a combination of high strength, hardness, and corrosion resistance. The alloy’s composition typically includes 17% chromium, 4% nickel, 3-5% copper, with smaller amounts of niobium, manganese, silicon, and carbon. The similar alloys including the below:
- 15-5 PH stainless steel: Enhanced toughness compared to 17-4 PH.
- 13-8 Mo stainless steel: Higher strength and better toughness.
- 17-7 PH stainless steel: Higher strength but reduced corrosion resistance.

Spherical 17-4 PH Stainless Steel Powder Reference
- 17–4 PH (precipitation hardening) stainless steel is commonly used for the fabrication of complicated molds with conformal cooling channels using laser powder bed fusion process (L-PBF). However, their microstructure in the as-printed condition varies notably with the chemical composition of the feedstock powder, resulting in different age-hardening behavior.
- In the present investigation, 17–4 PH stainless steel components were fabricated by L-PBF from two different feedstock powders, and subsequently subjected to different combinations of post-process heat treatments. It was observed that the microstructure in as-printed conditions could be almost fully martensitic or ferritic, depending on the ratio of Creq/Nieq of the feedstock powder.
The main stainless steel alloys are categorized into five primary groups based on their crystalline structure and composition:
Austenitic Stainless Steels:
- 304 (18/8): Most common, good corrosion resistance, weldability.
- 316: Contains molybdenum for improved corrosion resistance, especially against chlorides.
- 310: High temperature resistance.
Ferritic Stainless Steels:
- 430: Good corrosion resistance, formability.
- 409: Used in automotive exhausts, good heat resistance.
Martensitic Stainless Steels:
- 410: Basic martensitic grade, good hardness and corrosion resistance.
- 420: Higher carbon content, used in cutlery.
Duplex Stainless Steels:
- 2205: Balanced austenitic and ferritic properties, excellent corrosion resistance.
- 2507: Higher alloy content for improved strength and corrosion resistance.
Precipitation-Hardening Stainless Steels:
- 17-4 PH: Combines high strength, hardness, and corrosion resistance.
- 15-5 PH: Similar to 17-4 PH but with better toughness.
These alloys are widely used in industries such as construction, automotive, aerospace, medical, and food processing due to their varying properties tailored for specific applications.
Stainless precipitation hardened steel 17-4PH, 17-4 PH, 1.4542, X5CrNiCuNb17-4-4, AISI 630, UNS S17400 according to EN 10088-1, ASTM A564.
17-4 PH is a Martensitic, precipitation hardened steel that combines high strength and hardness with excellent corrosion resistance. 316L, on the other hand, is an Austenitic chrome nickel steel. 316L also offers excellent corrosion resistance and low levels of carbon which make it great for welding.
