What is Stainless Steel 304H Plate?

Stainless Steel 304H is a higher carbon version of SS304, specifically designed to provide higher strength at elevated temperatures. It is an austenitic stainless steel alloy, renowned for its excellent resistance to corrosion, heat, and oxidation. The SS304H plate is extensively used in industries that require high strength and durability, such as power plants, chemical processing, food processing, and construction.

Applications of SS304H Plate

The versatility of SS304H plates makes them ideal for several high-demand applications:

• Heat exchangers and boilers: The ability to withstand elevated temperatures makes SS304H plates perfect for heat exchangers, reactors, and boiler systems.

• Pressure vessels: SS304H is commonly used for manufacturing pressure vessels due to its mechanical strength at high temperatures.

• Chemical and petrochemical industries: SS304H’s resistance to oxidation and corrosion makes it a reliable choice for pipes, fittings, and equipment in the chemical industry.

• Food processing and pharmaceuticals: The high resistance to corrosion ensures that SS304H is used in food-grade equipment and pharmaceutical manufacturing.

Corrosion Resistance of SS304H

One of the primary reasons SS304H stainless steel plates are preferred in various industries is their excellent corrosion resistance. The high chromium content, along with nickel, makes 304H plates highly resistant to rust and oxidation, even in aggressive environments. It is particularly resistant to:

• Acids such as sulfuric acid and phosphoric acid.

• Chlorides, making it a good choice for marine environments.

• High temperatures and oxidation in outdoor applications.

Difference Between SS304H and SS304

Both SS304H and SS304 are part of the austenitic stainless steel family, but there are key differences between the two:

• Carbon Content: The most significant difference lies in the carbon content. SS304H contains a higher percentage of carbon (0.04% to 0.10%) compared to SS304 (0.08% maximum). This increase in carbon enhances its strength at high temperatures.

• Heat Resistance: SS304H plates have better heat resistance than SS304 plates, making SS304H a preferred option for high-temperature applications.

• Mechanical Properties: SS304H offers superior strength and mechanical properties at elevated temperatures when compared to SS304.

Properties of SS304H Plate

SS304H plates possess remarkable properties, making them one of the best options for high-performance applications:

• High Strength: The added carbon content provides increased strength, especially at temperatures above 500°C.

• Durability: Excellent mechanical properties, ensuring long-term durability in harsh conditions.

• Ductility: SS304H maintains its ductility even under extreme conditions.

• Weldability: This material has good weldability, making it easy to work with during fabrication.

SS304H Chemical Composition

The chemical composition of SS304H plates typically includes the following elements:

• Chromium: 18-20%

• Nickel: 8-12%

• Carbon: 0.04-0.10%

• Manganese: 2.0%

• Silicon: 0.75%

• Phosphorus: 0.045% max

• Sulfur: 0.03% max

These elements give SS304H its excellent strength, resistance to corrosion, and high-temperature stability.

SS304H Mechanical Properties

The mechanical properties of SS304H plates are critical for their use in high-temperature and high-stress environments:

• Tensile Strength: 520 MPa minimum

• Yield Strength: 205 MPa minimum

• Elongation: 40% minimum

• Hardness: Brinell hardness of 201 HB

These properties ensure SS304H plates remain durable and stable under mechanical stress and elevated temperatures.

SS304H Plate Equivalent Grades

When looking for SS304H plates, it is essential to know their equivalent grades in different standards:

• AISI 304H (American)

• UNS S30409 (Unified Numbering System)

• EN 1.4948 (European Standard)

• DIN 1.4948 (German Standard)

• JIS SUS 304H (Japanese Standard)

SS304H Plate Heat Resistance

One of the standout features of SS304H plates is their heat resistance. These plates can perform well at temperatures up to 870°C in intermittent service and 925°C in continuous service. This high-temperature resistance makes SS304H an ideal choice for applications like boilers, heat exchangers, and furnaces.

SS304H Plate Manufacturing Process

The manufacturing process of SS304H plates involves the following stages:

• Hot Rolling: The material is passed through rollers at high temperatures to form a flat plate.

• Annealing: After rolling, the plates are heat-treated to reduce hardness and improve ductility.

• Pickling: To remove scales and impurities, the plates undergo an acid cleaning process.

• Cold Rolling: In some cases, cold rolling is used to further refine the thickness and finish of the plates.

SS304H Plate Price

The price of SS304H plates varies depending on factors such as size, thickness, and quantity. To get an accurate price quote for SS304H plates, it’s best to contact a reliable supplier like Sachiya Steel International Private Limited.

SS304H Plate Versus SS304L

While SS304L offers better weldability due to its low carbon content, SS304H is better suited for high-temperature applications because of its higher carbon content. For applications involving extreme heat, SS304H plates are the preferred choice.

SS304H Plate Weight Calculator

To help you estimate the weight of SS304H plates, you can use a simple plate weight calculator that factors in the thickness, length, and width of the plate. This allows for accurate material estimation for your projects.

For example, let’s assume you need a SS304H plate that is:

• Length: 2 meters (2000mm)

• Width: 1 meter (1000mm)

• Thickness: 10mm

Using the formula for calculating the weight of stainless steel plates:

$$\text{Weight}=\text{Length}\times \text{Width}\times \text{Thickness}\times \text{Density}$$

Where the density of SS304H is approximately 7.93 g/cm³.

So, substituting the dimensions:

Weight=2000mm×1000mm×10mm×7.93g/cm

First, we need to convert the units to cm:

• Length = 2000mm = 200cm

• Width = 1000mm = 100cm

• Thickness = 10mm = 1cm

Now, calculate the weight:

Weight=200×100×1×7.93g=158600grams=158.6kg

So, the weight of this SS304H plate is approximately 158.6 kg.
