2205 Duplex Stainless Steel Plate Supplier
Bao Steel supplies 2205 duplex stainless steel plate for marine structures, offshore parts, chemical equipment, pressure-related components, desalination systems, tanks, heat exchanger parts and high-corrosion industrial applications. Compared with 304 and 316 stainless steel plate, 2205 is usually reviewed when the project needs a stronger duplex stainless route, better resistance in chloride-related environments, or a higher-strength material option. You can send grade, thickness, width, length, surface finish, cutting requirement, MTC requirement, packing method and destination so we can check availability and quotation details.
Choose 2205 When 304 or 316 May Not Match the Service Condition
2205 duplex stainless steel plate is normally selected by corrosion environment, strength requirement, chloride exposure, welding condition, plate thickness, inspection documents and final application. It should not be quoted only as a decorative stainless plate. For most thick plate orders, NO.1 hot rolled pickled surface is more common, while 2B or other finished surfaces should be confirmed by thickness and processing feasibility.
2205 Duplex Stainless Steel Plate
Use 2205 when the project needs duplex stainless steel for strength and demanding corrosion environments.
View 2205 Plate →UNS S32205 / S31803 Route
Confirm whether the order requires UNS S32205, UNS S31803, EN 1.4462 or project-specified equivalent.
Check Grade Route →Hot Rolled NO.1 Plate
For thicker duplex stainless plate, industrial fabrication, tanks, pressure-related parts and cut plate orders.
View Hot Rolled Plate →Cold Rolled 2B Plate
For cleaner surface or thinner plate requirements where cold rolled 2205 availability should be checked.
View Cold Rolled Route →Marine / Offshore Route
Use this route when the order serves marine, offshore, coastal or chloride-related applications.
View Marine Route →Chemical Equipment Plate
For tanks, process equipment, heat exchanger parts and corrosion-resistant industrial systems.
View Chemical Route →Cut-to-Size Plate
For custom dimensions, project cutting, edge protection, MTC matching and export preparation.

Review 316 / 316L when the service condition does not require the duplex 2205 route.
Compare 316 / 316L →2205 Plate Quotation Should Confirm Duplex Grade, Service Environment and Document Requirements
The main risk in 2205 duplex stainless steel plate purchasing is treating it like ordinary stainless plate. A practical quotation should confirm grade route, thickness, surface, cutting requirement, MTC, mechanical property requirement, corrosion environment and whether 2205 is required instead of 316 / 316L.
Duplex Grade Route
Confirm whether the order requires 2205, UNS S32205, UNS S31803, EN 1.4462 or another equivalent duplex grade.
Application Environment
Confirm whether the plate is used in marine, offshore, chloride-related, chemical or high-corrosion industrial conditions.
Thickness and Cutting
Send exact thickness, width, length, tolerance and cut-to-size requirement because duplex plate orders are often project-specific.
MTC and Traceability
Confirm MTC, heat number, grade marking, chemical composition, mechanical properties and third-party inspection needs.
2205 Duplex Stainless Plate vs 304 / 316 Stainless Plate
2205 should be selected according to service environment and project requirement, not only by price. It is normally reviewed when 304 is not enough and 316 / 316L may still not meet the corrosion or strength requirement.
| Route | Common Buyer Requirement | Typical Application | Quotation Check Point |
|---|---|---|---|
| 2205 Duplex Stainless Steel Plate | Duplex stainless steel plate for higher strength and more demanding corrosion environments. | Marine structures, offshore parts, chemical equipment, desalination systems, pressure-related components and industrial tanks. | Confirm grade equivalent, MTC, thickness, surface, cutting, corrosion environment and inspection requirements. |
| UNS S32205 / UNS S31803 | Buyer or project document may specify one of these 2205-related grade routes. | Project material lists, engineering drawings, chemical equipment, marine structures and pressure-related components. | Confirm exact grade on PO and MTC. Do not assume all 2205 inquiries accept the same equivalent route. |
| Hot Rolled NO.1 Plate | Thicker duplex stainless plate for industrial fabrication and cut-to-size orders. | Chemical tanks, pressure-related parts, marine fabrication, heavy plate parts and project cutting. | NO.1 / hot rolled pickled surface is more common for thicker plate; confirm surface acceptance before quotation. |
| Cold Rolled 2B Plate | Cleaner surface or thinner duplex stainless plate requirement. | Equipment panels, corrosion-resistant components and thinner duplex stainless applications. | Confirm stock availability, thickness feasibility, surface protection and packing method. |
| Marine / Offshore Route | Stronger route for chloride-related or seawater-adjacent environments. | Marine structures, offshore platforms, port facilities, seawater systems and coastal industrial equipment. | Confirm actual exposure condition, design standard and whether 316 / 316L is insufficient. |
| Chemical Equipment Route | Material route for chemical processing, tanks, process equipment and aggressive industrial environments. | Chemical tanks, process equipment, heat exchanger parts, industrial covers and corrosion-resistant fabricated parts. | Confirm medium, temperature, drawing requirement, MTC and third-party inspection requirement. |
| 316 / 316L Stainless Steel Plate | Higher corrosion resistance than 304 and common route for marine, coastal and chemical use. | Marine parts, coastal fabrication, chemical equipment and welded stainless parts. | Use 316 / 316L when the service condition does not require duplex 2205. |
| 304 / 304L Stainless Steel Plate | General stainless steel plate for broad industrial and fabrication applications. | General equipment, kitchen equipment, architectural parts, tanks and fabrication components. | Use 304 / 304L when chloride resistance and high-strength duplex route are not required. |

Common Questions from 2205 Duplex Stainless Steel Plate Buyers
When should I choose 2205 duplex stainless steel plate?
Choose 2205 when the project requires a duplex stainless route for higher strength, chloride-related corrosion resistance, marine use, chemical equipment or more demanding industrial environments where 304 or 316 may not be enough.
Can 2205 replace 316 / 316L stainless steel plate?
2205 should be reviewed when the service condition requires duplex stainless performance, but it should not be used only as a casual substitute. The project document, environment, design requirement and MTC route should be confirmed first.
What grade should I write on the inquiry: 2205, UNS S32205 or UNS S31803?
Send the exact grade from your drawing, project material list or purchase specification. If the project allows equivalent grades, state the acceptable alternatives clearly before quotation.
Can 4–100mm 2205 plate be supplied with all surface finishes?
No. Surface feasibility depends on thickness, rolling process and processing route. Thick 2205 duplex plate is commonly supplied with NO.1 hot rolled pickled surface, while 2B, BA, mirror, hairline or brush finishes should be confirmed by actual thickness and processing feasibility.
What information should I send for quotation?
Send grade, thickness, width, length, surface finish, cutting request, quantity, MTC requirement, application environment, packing method, destination port and delivery schedule.
