20mm Thick Stainless Steel Plate

20mm thick stainless steel plate belongs to heavy hot rolled stainless steel plate. It is widely used in structural engineering, attrezzature a pressione, produzione di macchinari, and heavy industrial applications due to its high strength, rigidity, and excellent load-bearing capacity.

Unlike thin stainless steel sheets, 20mm plates are mainly produced through hot rolling processes and are supplied in standard or customized cut sizes depending on project requirements.

Standard Thickness Category

20mm stainless steel plate is part of the heavy plate range:

• Thin plate: 0.3mm – 3.0mm (laminato a freddo)
• Medium plate: 3mm – 12mm (laminato a caldo)
• Heavy plate: 12mm – 100mm+ (laminato a caldo)

👉 20mm belongs to heavy hot rolled stainless steel plate

Common Standard Widths

Hot rolled stainless steel plates are usually produced in wide slab formats and then cut into standard widths.

Typical widths include:

In heavy industrial supply, wider plates (fino a 2500 mm or customized widths) are also available.

Common Standard Lengths

Length is often flexible and can be cut according to project requirements.

Typical lengths include:

Longer plates (fino a 12000 mm) can be produced for large engineering structures.

Typical Supply Forms

20mm stainless steel plates are generally supplied in:

• Hot rolled plate (Superficie n.1)
• Cut-to-size plate
• Rough machined plate
• Stato ricotto
• Pickled surface condition

Common Edge Types

Depending on processing requirements:

• Bordo del mulino (standard hot rolled edge)
• Sheared edge (cut to size)
• Flame cut edge (heavy fabrication use)
• CNC cut edge (componenti di precisione)

Weight Reference (Approximation)

For 20mm stainless steel plate:

• Densità: ~7,93 g/cm³
• Weight formula: thickness × width × length × density

Example reference:

• 20mm × 1500mm × 6000mm ≈ 1416 kg per piece (ca.)

Common Applications of 20mm Stainless Steel Plate

Due to its thickness and strength, 20mm stainless steel plate is widely used in heavy-duty industries:

• Gusci di recipienti a pressione
• Serbatoi di stoccaggio chimici
• Shipbuilding structural parts
• Bridge and construction supports
• Heavy machinery base plates
• Mining equipment components
• Offshore platform structures
• Boiler and heat exchanger shells
• Nuclear and power plant components
• Industrial mold bases
