What is Corten A Steel Plate?
Corten A Steel Plate is a type of weather-resistant steel that contains a blend of copper, nickel, and chromium with phosphorus. It is commonly used in container manufacturing, rolling stock, oil rigs, harbor construction, oil platforms, and other structural parts affected by hydrogen sulfide corrosion in petrochemical equipment. Corten A steel plate is known for its corrosion resistance and forms a protective layer known as a 'patina' when exposed to moisture, enhancing its atmospheric corrosion resistance compared to standard steel. This steel grade does not rust when exposed to moisture, and the rust layer protects the steel beneath, ensuring its strength. Corten A steel plate is aesthetically pleasing and has been used in various architectural applications, including sculptures and bridges, due to its high resistance to atmospheric weathering.

What is Corten B Steel Plate?
Corten B Steel Plate is a great example of weather-resistant steel which has high tensile strength and high toughness. The plate is made up of a copper chromium alloy steel which is characterized by its outstanding resistance to atmospheric weathering as compared to other unalloyed steels. Corten B steel Plate chemical composition includes copper, chromium and phosphorus as they go into making this metal more resistant to corrosion. This type of steel develops a protective layer when exposed to atmospheric elements, which eliminates the need for maintenance like painting, making it a cost-effective alternative to other structural steels.

Difference Between Corten A Steel Plate & Corten B Steel Plate
Applications:
Corten A steel is commonly used in outdoor structures, such as buildings, bridges, and sculptures, due to its superior resistance to atmospheric corrosion.
Corten B steel is often used in applications where higher strength and improved weldability are required, such as structural components in heavy-duty machinery or construction equipment.
Weathering Properties:
Both Corten A and Corten B steel plates develop a protective layer of rust when exposed to the atmosphere, which acts as a barrier against further corrosion. However, the rate at which this patina forms may vary slightly between the two types.
