Stainless Steel 409 Plates Manufacturers, Suppliers, Stockists & Exporters in India
Stainless Steel 409 Plates are ferritic stainless steel plates known for their good resistance to oxidation, corrosion, and high-temperature conditions. Grade 409 is a titanium-stabilized stainless steel that offers a practical combination of strength, weldability, durability, and cost-effectiveness. These plates are commonly selected for applications where moderate corrosion resistance and resistance to elevated temperatures are required.
Stainless Steel 409 Plates are widely used in automotive exhaust systems, industrial equipment, heat-resistant components, chemical processing equipment, and fabrication applications. Their ferritic structure provides good resistance to stress corrosion cracking and makes the material suitable for environments involving thermal cycling and elevated temperatures.
A M Industries is a manufacturer, supplier, stockist, and exporter of Stainless Steel 409 Plates, supplying material to customers across India and international markets. The company provides stainless steel products manufactured and supplied according to applicable national and international specifications for industrial applications.
Stainless Steel 409 Plates
Stainless Steel 409 is generally classified as a ferritic stainless steel containing chromium and titanium as important alloying elements. Titanium stabilizes the carbon and nitrogen content, improving resistance to sensitization during welding and elevated-temperature service.
The material is particularly suitable where extreme corrosion resistance is not required but better oxidation resistance, durability, and heat resistance are important. Stainless Steel 409 Plates can be supplied in different thicknesses, widths, lengths, and surface finishes according to project requirements.
Chemical Composition of Stainless Steel 409
The chemical composition of Stainless Steel 409 contributes to its ferritic structure and performance in high-temperature applications. Typical alloying elements include chromium, titanium, carbon, manganese, silicon, phosphorus, sulfur, and iron.
| Element | Typical Requirement |
|---|---|
| Carbon | ≤ 0.08% |
| Manganese | ≤ 1.00% |
| Silicon | ≤ 1.00% |
| Phosphorus | ≤ 0.045% |

Manufacturing Process of Stainless Steel 409 Plates
The manufacturing process begins with carefully selected raw materials and alloying elements. These materials are melted in an electric furnace and refined to achieve the required chemical composition.
After melting and refining, the steel is cast into slabs. The slabs are subsequently reheated and hot rolled to obtain the required plate dimensions. Depending on the required specification, additional processing such as annealing, pickling, leveling, cutting, and surface finishing may be performed.
Before dispatch, Stainless Steel 409 Plates can undergo dimensional inspection, chemical analysis, mechanical testing, hardness testing, and visual inspection. Inspection documentation can be provided according to customer requirements.
Surface Finish Available for Stainless Steel 409 Plates
The surface finish required for Stainless Steel 409 Plates depends on the application and fabrication process. Common finishes can include hot-rolled, annealed and pickled, and other specially processed surfaces.
A suitable finish can help improve appearance, cleanliness, fabrication performance, and resistance to surface contamination. Customers should specify the required finish, thickness, dimensions, and applicable standard when placing an order.
Stainless Steel 409 Plates Standards
Stainless Steel 409 Plates can be supplied according to recognized stainless steel standards and specifications depending on the required application.
Common specifications associated with Grade 409 include ASTM A240 / ASME SA240 for stainless steel plate, sheet, and strip intended for pressure vessels and general applications.
Other applicable standards may be considered depending on the required product form, application, and destination market. Customers should confirm the required ASTM, ASME, EN, DIN, or other specification before procurement.
Stainless Steel 409 Plates Sizes
Stainless Steel 409 Plates can be supplied in standard and customized dimensions. The available size depends on manufacturing capability, stock availability, and customer requirements.
Typical supply parameters include:
| Parameter | Availability |
|---|---|
| Thickness | As required |
| Width | Standard or customized |
| Length | Standard or customized |
| Surface | Hot Rolled / Processed |
| Edge | Mill Edge / Cut Edge |
| Form | Plates |
| Grade | Stainless Steel 409 |
For large industrial projects, plates can be cut to specified dimensions to reduce fabrication wastage and improve material utilization.
Applications of Stainless Steel 409 Plates
Stainless Steel 409 Plates are widely used in applications requiring economical stainless steel with good oxidation and heat resistance. One of the most recognized uses of Grade 409 is in automotive exhaust systems.
Typical applications include:
-

Benefits of Using Stainless Steel 409 Plates
The combination of chromium, titanium stabilization, and ferritic metallurgy gives Stainless Steel 409 Plates a useful balance of performance and cost.
For applications exposed to heat and atmospheric conditions, the grade provides better oxidation resistance than ordinary carbon steel. Its comparatively economical alloy content can also make it an attractive option when the corrosion requirements do not justify a higher-alloy stainless steel.
Good weldability and fabrication characteristics further support its use in manufactured components and fabricated assemblies.
