Enquire NowAISI 410 represents the foundational grade of martensitic stainless steel, containing a nominal 11.5% to 13.5% chromium alongside controlled carbon levels. This unique chemical composition permits a full microstructural phase transformation from austenite to martensite upon rapid cooling (quenching) from austenitizing temperatures (typically between 925°C and 1010°C).
Unlike austenitic grades (such as 304 or 316), AISI 410 responds exceptionally well to heat treatment, enabling mechanical engineers to tailor yield strength, ultimate tensile strength, and hardness metrics. By tempering quenched 410 stainless steel sheets or plates in specific thermal windows (595°C to 760°C), the material achieves an optimal balance of structural ductility, impact toughness, and wear resistance.
Our Chinese production facility specializes in optimizing the rolling and thermal histories of 410 steel. By using advanced metallurgy practices, we minimize residual elemental segregation, preventing localized galvanic action and ensuring consistent machining behavior across the plate surface.
Analyze how AISI 410 compares structurally and mechanically with standard austenitic, ferritic, and duplex stainless steels.
| Steel Grade | Microstructure | Cr Range (%) | Ni Range (%) | Tensile Strength (MPa) | Hardness (HB max) | PREN Value | Key Application Focus |

| AISI 304 | Austenitic | 18.0 - 20.0 | 8.0 - 10.5 | 515 - 620 | 201 | 18 | Food Handling, General Chemical |
| AISI 316L | Austenitic | 16.0 - 18.0 | 10.0 - 14.0 | 485 - 580 | 217 | 23 | Marine Environments, Petrochemical |
| AISI 430 | Ferritic | 16.0 - 18.0 | ≤ 0.75 | 450 - 600 | 183 | 16 | Automotive Trim, Appliances |

Our ongoing metallurgical innovations and production strategies address demanding global application parameters.
Applying advanced Argon Oxygen Decarburization (AOD) refining cycles minimizes residual interstitial elements like nitrogen, oxygen, and carbon. This process enhances structural impact properties at lower service temperatures.
Thermo-Mechanical Controlled Processing (TMCP) methods reduce the growth of secondary carbides, ensuring structural homogeneity during plate fabrication and processing cycles.
Using trivalent chromium coatings and advanced nitric-free passivation techniques provides reliable rust protection while complying fully with RoHS and REACH standards.
How AISI 410 and our performance alloys solve structural and environmental challenges in critical engineering sectors.
Type 410 provides high thermal conductivity and resists thermal scaling up to 705°C, making it suitable for steam condenser plates, tubes, and boiler support structures.
Ensures structural strength and resists atmospheric moisture. Its mechanical stability under fluctuating temperatures makes it a reliable component in industrial cooling loops.
Performs reliably in diluted organic and mineral acid processing systems. Provides reliable resistance against hydrogen-induced cracking in sulfurous atmospheres.
Provides wear-resistant surfaces for sorting machinery and non-critical process areas, balancing cost-efficiency with food safety standards.
Excellent base material for high-strength utility piping. Smooth internal surfaces support cleaning processes like Clean-in-Place (CIP).
Resists particulate erosion, dry steam wear, and mechanical fatigue. Suitable for manufacturing turbine blades and heat recovery units.
High yield strength and hardness are critical for gate valve components, pump shafts, and fractionating trays handling sour petroleum fluids.
