SA285 is a pressure vessel carbon steel plate utilized for applications requiring low or intermediate tensile strength. This grade is used in the manufacture of storage tanks and low pressure, temperature controlled vessels.

A285 refers to a carbon steel plate that conforms to the specifications set forth by the ASTM A285/A285M standard. This standard covers pressure vessel carbon plates with low to intermediate tensile strength intended for fusion-welded pressure vessels.

The A285 steel plates are primarily used in the fabrication of boilers, storage tanks, and similar equipment that require high-temperature service. These plates are available in different grades, designated as A285 Grade A, Grade B, and Grade C. Each grade has specific chemical composition and mechanical properties to ensure suitability for specific pressure vessel applications.
