S30408 Stainless Steel Plates
S30408 Stainless Steel Plates are duplex stainless steel plates combining austenitic and ferritic structures, designed for excellent corrosion resistance, high mechanical strength, and long-term durability. Compared with standard 304 stainless steel, S30408 provides superior resistance to pitting, stress corrosion cracking, and crevice corrosion, especially in harsh chemical and marine environments.
These plates are manufactured using advanced rolling and heat treatment processes to ensure uniform thickness, stable mechanical properties, and high-quality surface finishes such as 2B, BA, and No.4. All products meet international standards including ASTM, AISI, and EN, ensuring reliable performance for demanding industrial applications.
Parameter

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.

FAQ
1. What is the difference between hot rolled and cold rolled stainless steel plates?
Hot rolled plates are processed at high temperatures and typically have a rougher surface (NO.1 finish), while cold rolled sheets offer smoother surfaces and tighter tolerances.

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.
