ASTM 304 304L 316L Stainless Steel Plate with 2B Surface Finish and 3–50 mm

Our 300 Series stainless steel plates are manufactured in accordance with ASTM standards and are available in multiple grades, including 304, 304L, 304N, 316L, and 904L. Featuring a 2B surface finish, these plates provide a smooth appearance suitable for fabrication, welding, machining, and structural applications.

With thicknesses ranging from 3 mm to 50 mm, widths from 1000 mm to 2000 mm, and customizable lengths up to 6000 mm, the plates can be supplied for engineering construction, industrial fabrication, processing equipment, and architectural projects.

Processing services such as cutting, bending, punching, welding, and decoiling are available according to project drawings.

Selecting the appropriate stainless steel grade is critical for achieving the required corrosion resistance, fabrication performance, and service life.

For example:

• 304 is widely used for general industrial and architectural applications.
• 304L offers lower carbon content, making it suitable for welded structures where post-weld corrosion resistance is required.
• 316L contains molybdenum, providing improved resistance in chloride-containing environments.
• 904L is commonly selected for aggressive chemical processing environments requiring enhanced corrosion resistance.

Choosing the correct grade according to the working environment helps avoid unnecessary material costs while meeting engineering requirements.

To meet different fabrication and construction requirements, we provide stainless steel plates in multiple grades and dimensions with flexible processing options.

Our solution includes:

• ASTM-compliant 300 Series stainless steel plates
• 2B surface finish suitable for further fabrication
• Thickness range from 3 mm to 50 mm
• Widths up to 2000 mm
• Custom lengths according to project requirements
• CNC cutting, bending, punching, and welding support
• Export-standard seaworthy packaging

Each order can be manufactured according to the customer's drawing or material specification.

These stainless steel plates are widely used in:

• Engineering construction
• Structural fabrication
• Industrial equipment
• Food processing equipment
• Chemical processing facilities
• Architectural decoration
• Pressure vessel components
• Machinery manufacturing
• Storage tanks
• General metal fabrication

The manufacturing process begins with selecting the required stainless steel grade according to the application's corrosion resistance and mechanical property requirements.

After cold rolling, the plates receive a 2B surface finish, providing a smooth and uniform surface suitable for machining and fabrication. According to customer requirements, plates can then undergo cutting, bending, punching, or welding before packaging for export.

This processing flow allows customers to receive materials that closely match their fabrication needs, reducing additional processing time after delivery.

When selecting a stainless steel plate, consider the following factors:

• 304 -- General engineering and indoor applications
• 304L -- Welded structures requiring reduced carbide precipitation
• 316L -- Marine, coastal, and chloride environments
• 904L -- Chemical processing and highly corrosive environments

Select thickness according to structural load, machining allowance, and design requirements.

The 2B finish is suitable for fabrication and industrial applications. If decorative appearance is required, finishes such as BA, No.4, HL, or Mirror may be considered separately.

Confirm whether cutting, welding, bending, or punching services are required before production to improve processing efficiency.
