S30403 Stainless Steel Plates

S30403 Stainless Steel Plates
S30403 Stainless Steel Plates are duplex stainless steel plates featuring a balanced microstructure of austenite and ferrite. This combination provides excellent mechanical strength, superior corrosion resistance, and high durability, especially in chloride-rich and harsh chemical environments.
Compared with standard 304 stainless steel, S30403 offers improved resistance to pitting, crevice corrosion, and stress corrosion cracking. Its duplex structure ensures higher yield strength and good weldability, making it suitable for structural and industrial applications.
Manufactured using advanced rolling techniques, our S30403 stainless steel plates maintain precise thickness, consistent mechanical properties, and high-quality surface finishes such as 2B, BA, and No.4. All products comply with international standards including ASTM, AISI, and EN, ensuring reliable quality for global projects.

Applications

Hot rolled stainless steel plates are widely used across multiple industries due to their strength and corrosion resistance:

• Construction & Infrastructure – structural components, support frames, bridges
• Machinery Manufacturing – heavy equipment, industrial machinery parts
• Pressure Vessels & Tanks – storage tanks, boilers, chemical containers
• Energy & Power Industry – oil & gas equipment, power plant components
• ​Shipbuilding & Marine – decks, hull structures, offshore platforms

​Advantages

1. High Strength & Durability
Hot rolling enhances the mechanical properties, making the plates suitable for heavy-duty and load-bearing applications.
2. Excellent Corrosion Resistance
With grades like 304 and 316L, the plates perform well in corrosive and high-humidity environments.
3. Cost-Effective Solution
Compared to cold rolled sheets, hot rolled plates offer a more economical option for thick and structural uses.
4. Wide Thickness Range
Available in medium to heavy thicknesses, meeting diverse industrial requirements.
5. Good Workability
Suitable for further processing such as cutting, welding, and machining.

2. What grades of stainless steel plates do you supply?
We supply a wide range of grades including 304, 304L, 316L, 321, 310S, 309S, and duplex stainless steel.

3. What thickness range is available?
Our hot rolled stainless steel plates are typically available from 3 mm up to 50 mm or more, depending on grade and specification.

4. Do you support custom sizes?
Yes, we provide cut-to-length services and can customize dimensions based on your project requirements.

5. Do you offer fabrication services?
Yes, we provide complete metal fabrication services, including cutting, bending, welding, and CNC machining.
