1/4" Thick Stainless Steel Plate: Specifications, Weight, Pricing & Complete Buying Guide

A 1/4 inch thick stainless steel plate is one of the most commonly used thicknesses in industrial fabrication, equipment manufacturing, structural applications, and custom metal projects. With a thickness of approximately 6.35mm, it provides an excellent balance between strength, corrosion resistance, fabrication flexibility, and cost efficiency.

For engineers and buyers, selecting the correct stainless steel grade, size, surface finish, and supplier is essential to ensure long-term performance and control project costs.

What Is a 1/4" Thick Stainless Steel Plate?

A 1/4" stainless steel plate refers to a stainless steel plate with a nominal thickness of 0.25 inches, equal to approximately 6.35mm. It is widely used because it provides higher rigidity than thin sheets while remaining suitable for cutting, welding, machining, and forming.

Thickness	1/4 inch (6.35mm)
Material Type	Austenitic, Ferritic, Duplex Stainless Steel
Common Grades	304, 304L, 316, 316L, 2205
Supply Form	Plate, cut-to-size plate, fabricated components

Common Stainless Steel Grades for 1/4" Plates

The correct grade depends on corrosion conditions, mechanical requirements, and application environment.

Grade	Main Advantages	Typical Applications
304 Stainless Steel	Excellent corrosion resistance and fabrication performance	Industrial equipment, food processing, general fabrication
304L Stainless Steel	Improved welding performance	Welded structures and pressure equipment
316 Stainless Steel	Superior chloride and marine corrosion resistance	Marine, chemical, pharmaceutical applications
316L Stainless Steel	Low carbon version for welded corrosion-resistant equipment	Heavy welding projects
Duplex 2205	High strength and excellent corrosion resistance	Oil & gas, pressure vessels

1/4 Stainless Steel Plate Standard Sizes

Although custom sizes are available, many projects use standard dimensions to reduce material waste and simplify purchasing.

Standard Size	Metric Equivalent	Common Use
4 ft × 8 ft	1219 × 2438mm	General fabrication
5 ft × 10 ft	1524 × 3048mm	Large equipment manufacturing
Custom Size	According to drawing	OEM and engineering projects

Weight Calculation of 1/4" Stainless Steel Plate

Weight is an important factor when calculating transportation cost, structural load, and total project budget.

The approximate density of stainless steel is 7.93 g/cm³.

Plate Size	Thickness	Approximate Weight
4 ft × 8 ft	1/4" (6.35mm)	Approx. 173 kg
5 ft × 10 ft	1/4" (6.35mm)	Approx. 270 kg

Factors Affecting 1/4 Stainless Steel Plate Pricing

The price of 1/4 inch stainless steel plate is influenced by multiple factors. Material cost is only one part of the final quotation.

Cost Factor	Impact on Price
Stainless Steel Grade	316/316L costs more than 304 due to molybdenum addition
Nickel and Raw Material Market	Changes in alloy prices affect stainless steel costs
Surface Finish	2B, No.4, HL, and mirror finishes require different processing
Cutting Service	Laser cutting and custom shapes increase processing cost
Order Quantity	Bulk purchasing improves cost efficiency
Transportation	Heavy plates require optimized logistics planning
