ASTM A283 Grade A Steel Plate: Low‑Strength Carbon Steel for General Structural Fabrication

Posted:2026-01-16 14:33:18

ASTM A283 Grade A is a low‑strength carbon steel plate designed for general structural applications where moderate strength and good forming ability are required. With its low carbon content and high ductility, A283 Grade A is widely used in light‑duty structural components, welded parts, and non‑critical fabrication projects. It offers stable performance, easy processing, and cost‑effective material selection for construction and engineering industries.
