Common questions

Don't see yours? Email [email protected] — NDA on request.

What is CNPC Powder 18Ni300 maraging steel powder?

CNPC Powder 18Ni300 maraging steel powder is a maraging tool steel of the M300 / 1.2709 class with the highest strength and toughness of the steels in the range and good machinability before aging. It is a 15–53 µm cut for laser powder bed fusion, with 17.5–19.0% nickel, 8.5–9.5% cobalt, 4.6–5.2% molybdenum and 0.6–0.8% titanium, with iron as the balance. Typical uses listed by CNPC include molds and tool inserts, aerospace parts and medical devices.

What strength does printed 18Ni300 maraging steel reach with this powder?

According to the CNPC Powder catalog, as-built parts reach at least 1,198 MPa yield and 1,212 MPa tensile strength with 11% elongation. After solution at 800 °C for 1 hour and aging at 500 °C for 1 hour, the catalog lists at least 1,695 MPa yield, 1,958 MPa tensile and 5% elongation, with 595 HV1 hardness. These are minimum values from the data sheet, not design data, so qualify the alloy on coupons from your own machine and parameters.

How is 18Ni300 maraging steel heat treated after printing?

The catalog cycle is a solution treatment at 800 °C for 1 hour followed by aging at 500 °C for 1 hour. Machine before aging, because only light machining is practical afterwards. Maraging steel has limited corrosion resistance, so plan a coating or a protected environment for tools. Our materials engineer can help you plan test coupons and starting parameters before your first production build.

What particle size and flow does CNPC Powder 18Ni300 maraging steel powder have?

CNPC Powder 18Ni300 maraging steel powder is a 15–53 µm cut. The CNPC catalog specifies D10 of 10–25 µm, D50 of 25–40 µm and D90 of 40–60 µm, Hall flow of 20 s per 50 g or less, apparent density of at least 3.5 g/cm³ and sphericity of at least 80%. The certificate of analysis for your lot reports the measured particle size distribution and chemistry, and it is available on request.

Who makes CNPC Powder 18Ni300 maraging steel powder?

CNPC Powder makes it in China. Its catalog lists EIGA, VIGA, PREP and plasma spheroidization production lines and ISO 9001, ISO 14001, ISO 45001, ISO 13485 and IATF 16949 certificates, as stated by CNPC. Additive Plus sells and supports it in the US, with recommended starting parameters and the lot certificate on request.

How is CNPC Powder 18Ni300 maraging steel powder different from PowderRange M300 from Carpenter Additive?

Both are listed in the table at the top of this page with their prices, particle size and availability. CNPC Powder 18Ni300 maraging steel powder is made in China and is the lower-priced option per kilogram, while PowderRange M300 from Carpenter Additive comes with a named mill's published datasheet and ships from US stock when available. Choose by your program's country-of-origin rules, budget and timing.

How do I order CNPC Powder 18Ni300 maraging steel powder, and when does it ship?

Add it to the cart and pay by card or PayPal, choose Invoice me at checkout to receive an invoice for bank transfer, or send a purchase order to [email protected]. After you order, we confirm availability and the ship date by email. If that date does not work for you, we cancel the order and refund it in full. For 100 kg or more, ask us for a volume quote.
