310 Stainless Steel Powder
Stainless Steel 310 (UNS S31000) is a high-alloy austenitic stainless steel. Its core characteristics are its very high chromium and nickel content, which grant it excellent oxidation and carburization resistance, enabling it to operate continuously at high temperatures. Therefore, it is typically not used as a structural component but is rather a classic heat-resistant steel (or heat-strength steel).
Core Characteristics
Excellent Oxidation Resistance:This is its primary advantage. The high chromium content (approximately 25%) forms a dense and stable chromium oxide (Cr₂O₃) protective film on the material's surface. Even under cyclic high-temperature conditions, this film effectively prevents further oxidation of the internal metal. Its maximum continuous service temperature can reach approximately 1150°C.
Superior Carburization Resistance:In high-temperature environments with carbon-potential atmospheres rich in carbon monoxide, methane, etc. (such as heat treatment furnaces), many steel grades undergo "carburization," leading to surface embrittlement and cracking. The high nickel content of Stainless Steel 310 effectively resists the ingress of carbon elements, maintaining the material's toughness.
Good High-Temperature Strength:It maintains high creep strength and tensile strength at elevated temperatures, resisting deformation.
Corrosion Resistance:At room temperature, it exhibits good corrosion resistance to most organic acids, inorganic acids, and alkaline media. However, due to its higher cost, it is not typically used for room temperature corrosion environments unless high-temperature resistance is also required.
310 Stainless Steel Powder
310 stainless steel powder is an iron-based alloy powder with iron as the main component, chromium content of 24.0-26.0% and nickel content of 19.0-22.0%. Stainless steel 310/310S is an austenitic heat resistant alloy with excellent resistance to oxidation under mildly cyclic conditions through 2000°F. It has comparable corrosion resistance, superior resistance to oxidation and the retention of a larger fraction of room temperature strength than the common austenitic alloys like Type 304.
Preparation Process of 310 Stainless Steel Powder
① Using high-purity
chromium powder,
nickel powder, and iron powder melted into 310 stainless steel base material according to the standard composition ratio of 310 stainless steel;
② Producing spherical
310 stainless steel powder through gas atomization process;
③ Screening and vacuum packaging.

310 Stainless Steel Powder Application
310 stainless steel powder combines its exceptional heat-resistant properties with advanced near-net-shape technologies, achieving breakthroughs in design freedom and performance. It is particularly suitable for manufacturing complex-shaped high-temperature components that are unprocessable by traditional methods; providing cost-effective high-temperature surface protection for substrates; and producing small, heat-resistant parts in large volumes with high complexity. These applications are primarily concentrated in fields with stringent demands on material high-temperature performance, such as industrial furnaces, heat treatment, energy power, and aerospace. The details are as follows:
Additive Manufacturing (3D Printing) - Core Application
This is the highest-value application area for 310 stainless steel powder, used to manufacture high-performance, heat-resistant complex components.
Application Advantages:Manufacturing Complex Heat-Resistant Structures: Directly printing high-temperature components with complex internal channels and lightweight lattice structures, such as high-efficiency burners and heat exchangers.
Rapid Prototyping and Customization: Accelerating the design and testing cycle for new high-temperature resistant components.
Integrated Manufacturing: Consolidating multiple parts into a single printed component to avoid connection failure issues at high temperatures.
Typical Printing Processes:Laser Powder Bed Fusion (L-PBF/SLM): The most commonly used technique, capable of producing high-precision, dense 310 stainless steel parts.
Electron Beam Melting (EBM): Conducted in a vacuum and high-temperature environment, helps reduce residual stress and is suitable for manufacturing larger heat-resistant components.
Specific Application Components:Heat Treatment Industry: 3D printed furnace rolls, radiant tubes, baskets, fixtures, etc., enabling more efficient and durable designs.
Combustion Systems: High-temperature components for gas turbines, combustion chamber liners, nozzles, etc.
Aerospace: Certain heat-resistant components for engines, exhaust system parts.
Thermal Spraying and Surface Engineering
Using 310 stainless steel powder as a coating material to impart high-temperature resistance and oxidation resistance to substrate surfaces.
Application Processes:Atmospheric Plasma Spraying (APS)
High-Velocity Oxygen Fuel (HVOF) Spraying
Cold Spraying
Application Purpose:High-Temperature Protective Coatings: Spraying a 310 stainless steel coating onto the surface of carbon steel or low-alloy steel components (e.g., pipes, valves) that endure high temperatures, significantly extending their service life.
Carburization Resistance Protection: Applying coatings to the surface of tooling and fixtures within heat treatment furnaces to prevent carburization embrittlement.
Repair and Remanufacturing: Repairing expensive 310 stainless steel components that have failed due to high-temperature oxidation or wear.
Powder Metallurgy - Metal Injection Molding (MIM) and Pressing-Sintering
Used for producing small, complex, high-volume heat-resistant parts.
Application Processes:Metal Injection Molding (MIM): Mixing 310 stainless steel powder with a binder, injecting it into a mold to form, then debinding and sintering to obtain highly complex near-net-shape parts.
Pressing and Sintering: Forming by mold pressing followed by sintering, suitable for relatively simple-shaped parts.
Application Components:Small Heat-Resistant Parts: Such as guide balls, fasteners, sensor sleeves for heat treatment furnaces.
Automotive Engines: Some small heat-resistant sensor brackets or connectors.
Powder Metallurgy - Hot Isostatic Pressing (HIP)
Used for manufacturing fully dense, homogenized high-performance material billets.
Application Process:Loading 310 stainless steel powder into a canister and forming a dense billet via Hot Isostatic Pressing (high temperature and high pressure).
Application Purpose:Producing High-Performance Billets: The obtained material is segregation-free, isotropic, with more stable and reliable high-temperature performance, and can be used for subsequent forging or processing into critical components.
