What Are 304 Stainless Steel Sheets?
A 304 stainless steel sheet is a flat product made from Grade 304, an austenitic stainless steel containing chromium and nickel as its principal alloying additions. The grade is valued for its corrosion resistance, fabrication characteristics, and suitability across a broad range of indoor and outdoor industrial environments.
Grade 304 is commonly supplied as sheet, coil, and plate in different thicknesses and surface finishes. At Fortran Steel, our stainless steel sheet, coil, and plate range includes both 304 and 304L, with CR, HR, 2B, No. 4, No. 8, and BA finish options.
304 Stainless Steel Sheet Thickness and Sizes
The right SS 304 sheet thickness depends on the finished component, forming requirements, expected loads, and fabrication process. Thin sheets are commonly used for panels, cladding and formed components, while heavier material suits applications that need greater rigidity.
Fortran Steel supplies stainless steel sheets, coils and plates across a combined thickness range of 0.3 mm to 50 mm. Available widths include 625 mm, 750 mm, 1000 mm, 1250 mm, 1500 mm and 2000 mm.
When specifying 304 stainless steel sheet dimensions, buyers should consider four measurements and tolerances.
Thickness: Select thickness according to component strength, forming requirements, and the intended fabrication process.
Width: Available width should suit the component layout and planned cutting pattern.
Length: Sheet length can be selected according to fabrication and project requirements.
Tolerance: Required dimensional tolerances should be stated clearly for components where precision is important.
Custom dimensions: Project-specific sizing can reduce unnecessary cutting and material wastage during fabrication.
304 Stainless Steel Sheet Thickness and Weight Reference
The approximate weights below use a nominal density of 7.93 g per cubic centimetre and a reference sheet size of 1000 mm by 2000 mm. Actual weight can vary with dimensional and thickness tolerances.
Thickness | Reference Size | Approx. Weight | Typical Use |
0.5 mm | 1000 x 2000 mm | 7.93 kg | Liners and light panels |
0.8 mm | 1000 x 2000 mm | 12.69 kg | Kitchen and decorative components |
1.0 mm | 1000 x 2000 mm | 15.86 kg | Equipment panels and fabrication |
1.5 mm | 1000 x 2000 mm | 23.79 kg | Enclosures and formed components |
2.0 mm | 1000 x 2000 mm | 31.72 kg | Industrial fabrication |
3.0 mm | 1000 x 2000 mm | 47.58 kg | Machinery and heavier fabricated parts |
5.0 mm | 1000 x 2000 mm | 79.30 kg | Heavy fabricated components |
Thickness has a direct relationship with sheet weight. Doubling the thickness of an otherwise identical sheet approximately doubles its material weight, which should be considered when estimating handling, fabrication, and transportation requirements.

SS 304 Sheet Grades, Finishes & Specifications
304 is a stainless steel grade. Terms such as 2B, BA, and No. 4 describe surface finishes rather than separate SS sheet grades. Keeping this distinction clear helps buyers prepare accurate material specifications.
304 and 304L
304 and 304L belong to the same austenitic stainless steel family, but 304L has a lower maximum carbon content. The lower carbon level makes 304L particularly useful where welded fabrication and resistance to sensitisation are important considerations.
Common Surface Finishes
Finish | Characteristics | Common Applications |
2B | Smooth, cold rolled general purpose surface | Fabrication, equipment and industrial components |
BA | Bright, smooth and more reflective surface | Appliances, interiors and visible components |
No. 4 | Brushed matte appearance | Kitchens, equipment and architectural surfaces |
No. 8 | Highly polished mirror surface | Decorative and architectural applications |
HR | Hot-rolled surface for heavier material | Industrial and heavier fabrication |
CR | Cold-rolled material with closer surface and dimensional requirements | Sheet fabrication and finished components |
Cold-rolled material is generally associated with thinner gauges, tighter dimensional control, and smoother surfaces. Hot-rolled stainless steel is commonly used for heavier sections where surface appearance carries less importance than fabrication and structural requirements.
Applicable ASTM or ASME requirements should be confirmed against the exact product, thickness, and order specification rather than assumed from the 304 grade designation alone.
304 Stainless Steel Sheet Price: What Affects the Cost?
There is no single 304 SS sheet price that is accurate across every thickness, finish, and order quantity. Stainless steel markets change, while processing and commercial requirements also influence the final quotation.
Thickness: Material thickness changes sheet weight and the amount of stainless steel required per piece.
Sheet dimensions: Width and length determine the total material weight and can influence processing requirements.
Grade: 304 and 304L requirements should be clearly stated when requesting a quotation.
Surface finish: 2B, BA, No. 4, and polished surfaces involve different processing requirements.
Order quantity: Volume influences procurement, production planning, packing, and commercial terms.
Manufacturing route: Hot-rolled and cold-rolled products have different processing routes and cost structures.
Nickel market: Nickel is an important alloying element in 304, so raw material movements can influence stainless steel 304 sheet price.
Testing requirements: Additional testing, inspection, and certification requirements can contribute to order cost.
Logistics: Packaging, destination, and transportation requirements form part of the delivered cost.
For an accurate quotation, buyers should provide the grade, thickness, dimensions, finish, quantity, applicable specification, and delivery destination.
Applications of 304 Stainless Steel Sheets
The broad use of stainless steel sheet metal in manufacturing comes from its balance of corrosion resistance, fabrication characteristics, appearance, and cleanability. Grade 304 is particularly common across the following areas.
Food Processing
304 stainless steel sheets are widely used for food processing equipment, work surfaces, containers, panels, and machinery components. Their smooth surface is practical for equipment that requires regular cleaning and hygienic operating conditions.
Chemical & Pharmaceutical Equipment
Grade 304 is used for cabinets, equipment panels, vessels, and fabricated components in suitable chemical and pharmaceutical environments. Material selection should always account for the chemicals, concentrations, and operating temperatures involved.
Kitchen & Commercial Equipment
Sinks, counters, cabinets, splashbacks, commercial kitchen equipment and appliance components frequently use SS 304 sheets. Finishes such as 2B, BA, and No. 4 provide different surface characteristics for functional and visible components.
Architectural & Interior Applications
Grade 304 is used for wall panels, lift interiors, decorative features, trims and other architectural components. Finish selection becomes particularly important where appearance forms part of the design requirement.
Automotive & Industrial Components
Steel manufacturers use 304 stainless steel sheet for fabricated parts, covers, enclosures, brackets, and other industrial components. Thickness and finish can be selected according to forming, welding, and service requirements.
304 Stainless Steel Sheet vs 304 Stainless Steel Plate
Both products can be manufactured from the same 304 grade. The principal distinction is thickness and the product classification applied under the relevant specification.
Feature | 304 Stainless Steel Sheet | 304 Stainless Steel Plate |
Thickness | Generally thinner material | Generally thicker material |
Weight | Lower for the same width and length | Higher for the same width and length |
Formability | Commonly suited to bending and forming | Used where heavier material is required |
Finishes | 2B, BA, No. 4 and other finishes are common | HR and other specified finishes are common |
Typical uses | Panels, kitchens, equipment and fabricated components | Heavy equipment, tanks and industrial fabrication |
