The ‘L’ denotes lower carbon compared to 304 standard grade. The low carbon minimizes carbide precipitation and maximizes corrosion resistance. Powder metallurgy 304L provides a cost-effective alternative to 316L for non-critical applications not needing molybdenum alloying.
This article provides an in-depth look at 304L stainless steel powder covering composition, properties, processing, applications, specifications, suppliers, costs, and other technical details.
Composition
The nominal composition of 304L stainless steel powder is listed below:
Table: Typical composition of 304L stainless steel powder
| Element | Weight % |

Architectural panels, railings
Medical instruments and implants
Marine hardware, fittings, fasteners
Consumer products, appliances
Powder metallurgy mechanical parts
3D printing powders
304L provides cost-effective corrosion resistance versus 316L when molybdenum alloying is not needed for highly corrosive environments. The excellent polishability and non-magnetic properties also suits 304L for architectural cladding and hardware components.
Powder metallurgy is commonly used to produce small precision parts from 304L at high volumes versus machining. Additive manufacturing utilizes 304L powder for prototypes, tooling, and end-use components across industries.
Powder Manufacturing
304L stainless steel powder is commercially manufactured via gas atomization or water atomization processes.
In gas atomization, a high pressure inert gas stream disintegrates the molten metal into fine droplets, producing spherical powders ideal for additive manufacturing and MIM. Particle size distribution is controlled through process parameters.
Water atomization uses high pressure water jets to break up the metal stream into fine particles. This generates irregular, satellite particle shapes. The powder requires post-treatment for additive manufacturing.
Plasma atomization is sometimes used to produce very spherical, clean powders from a metal plasma stream in a controlled inert atmosphere. This ensures high purity and flowability.
Powder Specifications
304L stainless steel powder is commercially available in various size ranges, morphologies, and quality levels. Some typical powder specifications are below:
Table: 304L stainless steel powder specifications
| Attribute | Details |
| Particles sizes | 15-45 μm, 10-100 μm |
| Morphology | Spherical, irregular |
| Apparent density | 2.5-4.5 g/cm3 |
| Tap density | 4-5 g/cm3 |
| Hall flow rate | <30 s/50g |
| Purity | >99.5% |
| Oxygen content | <2000 ppm |
| Moisture content | <0.2% |
Smaller particle sizes below 45 μm are preferred for capturing fine features in additive manufacturing. Spherical particles provide good flowability. Apparent density correlates with powder packing efficiency.
High purity, low oxygen, and controlled moisture levels ensure quality sintered properties. Gas atomized powder offers the best specifications for critical applications.

Store in sealed containers in a cool, dry environment
Use inert gas purging or vacuum to prevent moisture pickup
Keep away from sparks, flames, and ignition sources
Ground all powder handling and transfer equipment
Avoid contact with contaminants like oil, grease, paints, etc.
Use PPE – mask, gloves, eye protection when handling powder
Powder spills should be promptly cleaned using non-sparking tools and HEPA vacuuming. Powders are moderately sensitive to moisture and air exposure. Proper storage is key.
Metal Injection Molding
304L is widely used for metal injection molding of small, complex parts leveraging powder metallurgy. Key considerations include:
