Summary of Stainless Steel Sheet Thickness Specifications

I. Common Thicknesses of Stainless Steel Sheets

Stainless steel sheets are available in various thicknesses, reflecting their wide range of applications and manufacturing requirements.

Starting with ultra-thin specifications, materials like 0.001″ stainless steel foil (304 - annealed) and 0.003″ stainless steel foil (316 - annealed and 304 - annealed) are available. These ultra-thin foils are often used in specialized contexts where minimal thickness is required alongside stainless steel properties (such as corrosion resistance), such as in certain precision components of electronic devices and high-end decorative sheets.

For slightly thicker specifications, the range of 0.15 - 8mm is common, suitable for many general industrial and architectural decoration needs. In the construction decoration sector, this thickness range ensures sufficient structural strength while meeting aesthetic requirements. In industrial applications, this thickness may be used for the casings of small equipment or internal structural components.

Additionally, thicknesses of 0.20 - 3mm are also prevalent, particularly in products requiring cold processing. This thickness range offers good plasticity and workability during manufacturing, making it ideal for kitchen utensils and simple mechanical parts, balancing ease of shaping with strength requirements.

Thicknesses of 0.3 - 2.0mm and 0.3mm - 3mm are also common in the market, widely used in industries such as automotive manufacturing (for certain parts) and furniture production (like components for stainless steel tables and chairs). Selecting the appropriate thickness depends on specific product designs and usage requirements, balancing cost, strength, and appearance.

II. Thickness Specifications for Different Types of Stainless Steel Sheets

Various types of stainless steel sheets have different thickness specifications due to their compositions, properties, and intended uses.

(A) Austenitic Stainless Steel Sheets

Austenitic stainless steels are among the most common types, such as 304 and 316 grades. The thickness specifications for 304 stainless steel sheets are diverse; for architectural decoration, thicknesses may range from 0.15 - 8mm, meeting needs for wall panels and ceiling decorations. In cookware manufacturing, 0.3 - 2.0mm thick 304 sheets are commonly used, ensuring strength during everyday use while being easy to shape, suitable for pots and utensils. Due to its superior corrosion resistance, 316 stainless steel is employed in environments requiring higher corrosion resistance, such as marine equipment or certain chemical processing components, with thicknesses around 0.2 - 3mm to ensure structural integrity while maximizing corrosion resistance.

(B) Martensitic or Ferritic Stainless Steel Sheets

Martensitic or ferritic stainless steels, such as 430, 420, and 410 grades, have specific thickness specifications. For instance, 410 stainless steel sheets may come in thicknesses from 0.28mm to 2.2mm, commonly used in applications where magnetic properties are needed, such as components of magnetic filters. With good hardness and certain magnetic characteristics, this thickness range meets the structural strength requirements of these components. 430 stainless steel sheets are often used in applications that require good corrosion resistance and heat resistance, typically available in thicknesses around 0.3 - 2.0mm, ideal for simple heat-resistant cookware or decorative components, balancing performance with cost and manufacturability.

(C) Duplex Stainless Steel Sheets

Duplex stainless steel sheets (containing 0.001 - 0.03% C, 0.05 - 1.5% Si, 0.10 - 3.00% Mn, 22.00 - 27.00% Cr, 4.00 - 7.00% Ni, 0.50 - 2.50% Mo, 0 - 1.50% W, and 0.10 - 0.25% N) can meet specific formulas (e.g., PREW = Cr + 3.3(Mo + 0.5W) + 16N) without solid solution heat treatment. These sheets are suitable for applications such as river structures, industrial machinery, and chemical industry vessels. While specific thickness specifications for duplex stainless steel sheets are not explicitly mentioned, they likely cover a wide range of thicknesses, from thinner sheets for protecting small internal structures of industrial machinery to thicker sheets for large river structures.
