🟧 Product Overview
ASTM A285 is a carbon steel pressure vessel grade designed for low‑to‑intermediate tensile strength applications. It is commonly used in welded pressure vessels, storage tanks, and industrial containers operating at moderate temperatures.
A285 is available in Grades A, B, and C, with Grade C offering the highest strength and being the most widely used. It provides good weldability and forming characteristics, making it suitable for non‑critical pressure applications.
