Storage Tank-Quality A285 Gr.C Carbon Steel Plate

ASTM A285 Grade C is a carbon steel plate specification used for pressure vessels and boilers, particularly for applications requiring low to intermediate tensile strength. It's known for its good formability and weldability, making it suitable for fusion-welded pressure vessels and piping systems. This grade is typically used in standard tanks and boilers rather than high-pressure applications due to its lower yield strength.

Product Description

1.What is the chemical composition of ASTM A285 Grade C steel?

ASTM A285 Grade C Chemical Composition (Weight %)

Element	Composition Range	Function
Carbon (C)	≤ 0.28%	Increases strength but reduces weldability if excessive
Manganese (Mn)	0.90-1.20%	Enhances toughness and hardenability
Phosphorus (P)	≤ 0.035%	Impurity – reduces cold brittleness
Sulfur (S)	≤ 0.035%	Impurity – affects hot workability
Silicon (Si)	0.15-0.40%	Deoxidizer – improves strength

2.What grade is A285 steel?

General Product Description. ASTM A285 is a specification for low and intermediate tensile strength carbon steel plates of pressure vessel quality for welded pressure vessel applications. The specification covers three grades, A, B, and C, which have different strength levels.
