321 Stainless Steel Plates
321 Stainless Steel Plates are titanium-stabilized austenitic stainless steel plates, designed for excellent resistance to intergranular corrosion, especially after exposure to temperatures in the 425–870°C range. Compared with 304 stainless steel, 321 offers enhanced thermal stability and excellent weldability due to the addition of titanium.
Our 321 stainless steel plates are manufactured using precise rolling processes, ensuring uniform thickness, consistent mechanical properties, and superior surface quality. Available in finishes such as 2B, BA, No.1, and No.4, these plates are ideal for applications requiring long-term performance at elevated temperatures.
All products comply with international standards including ASTM, AISI, and EN, guaranteeing reliable quality for global industrial applications.

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.
