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, معدات الضغط, تصنيع الآلات, 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 (المدرفلة على البارد)
• Medium plate: 3mm – 12mm (المدرفلة على الساخن)
• Heavy plate: 12mm – 100mm+ (المدرفلة على الساخن)

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 (ما يصل الى 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 (ما يصل الى 12000 مم) can be produced for large engineering structures.

Typical Supply Forms

20mm stainless steel plates are generally supplied in:

• Hot rolled plate (No.1 surface)
• Cut-to-size plate
• Rough machined plate
• Annealed condition
• Pickled surface condition

Common Edge Types

Depending on processing requirements:

• Mill edge (standard hot rolled edge)
• Sheared edge (cut to size)
• Flame cut edge (heavy fabrication use)
• CNC cut edge (مكونات الدقة)

Weight Reference (Approximation)

For 20mm stainless steel plate:

• كثافة: ~7.93 g/cm³
• Weight formula: thickness × width × length × density

Example reference:

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