ASTM A285GrC/A285 Grade C steel plate is a kind of material for pressure vessels and boilers in the standard ASTM A285/A285M. This type of steel plate is widely used in the oil, chemical, power generation, and other industries for the fabrication of welded pressure vessels and boilers due to its moderate strength level and excellent notch toughness.

Chemical Composition:

The chemical composition of ASTM A285GrC/A285 Grade C is designed to provide a combination of good weldability and high resistance to hydrogen-induced cracking. The typical chemical composition is as follows:

· Carbon (C): ≤ 0.28%

· Manganese (Mn): 0.90 - 1.50%

· Phosphorus (P): ≤ 0.035%

· Sulfur (S): ≤ 0.035%

· Silicon (Si): 0.13 - 0.45%

Mechanical Properties:

The mechanical properties of ASTM A285GrC/A285 Grade C are as follows:

· Tensile Strength: 55 - 75 ksi (380 - 515 MPa)

· Yield Strength: ≥ 30 ksi (205 MPa)

· Elongation in 2 inches (50 mm): ≥ 23%

Heat Treatment:

The steel plates are normally supplied in the as-rolled condition. Normalizing or stress-relieving heat treatment can be applied if required by the end-user or as per the manufacturing specifications.

Low-Temperature Impact Test:

ASTM A285GrC/A285 Grade C steel plates are often required to undergo a low-temperature impact test to ensure their toughness at sub-zero temperatures. The standard Charpy V-notch impact test is conducted at -20°F (-29°C) with a minimum average energy requirement.
