Characteristics and Application of 3D Printing Metal Powder 17-4PH stainless Steel Powder

(Characteristics and Application of 3D Printing Metal Powder 17-4PH stainless Steel Powder)

17-4PH stainless steel is a martensitic precipitation hardening stainless
steel, equivalent to the Chinese brand: 0Cr17Ni4Cu4Nb. 17-4PH precipitation
hardening steel with copper added. 17-4PH is used to manufacture shafts and
steam turbine parts.

Heat treatment specifications:

1. Rapid cooling at 1020～1060℃ for a solution

2. Ageing at 480℃, after solution treatment, air cooling at 470～490℃

3. Ageing at 550℃, after solution treatment, air cooling at 540～560℃

4. Ageing at 580℃, after solution treatment, air cooling at 570～590℃

5. Ageing at 620℃, after solution treatment, air cooling at 610～630℃

The main characteristics of 17-4PH stainless steel:

Corrosion resistance

The corrosion resistance of 17-4 PH stainless steel powder metallurgy alloy
is better than any other standard hardenable stainless steel. In most cases, its
corrosion resistance is no less than 304.

If there is a risk of stress corrosion cracking, the higher curing
temperature must be higher than 550ºC (1022ºF), preferably 590ºC (1094ºF), and
the best tempering temperature in the chloride medium is 550ºC-1022ºF.

This alloy is susceptible to corrosion or cracks corrosion in stagnant
seawater. Its corrosion resistance in the petrochemical industry, food
processing and paper industry is the same as 304L stainless steel powder
grade.

Welding performance

Any method can be used for welding in the state of reliable solution, ageing
or over ageing. There is no need to preheat before welding. If the weld strength
is required to be close to the power of the steel after ageing hardening, it
must be re-solutionized and ageing treated after welding. The steel is also
suitable for brazing, and the best brazing temperature is the solution treatment
temperature.

Application fields of 17-4PH stainless steel

Offshore platforms, helicopter decks, other platforms, food industry, pulp
and paper industry, aerospace (turbine blades), mechanical parts, nuclear waste
barrels.
