Kind Code:
A1
Abstract:
A weatherable steel plate and a manufacturing method therefor. The weatherable steel plate comprises the following components by mass percentage: 0.04-0.10% of C, 0.18‑0.35% of Si, 1.00‑1.60% of Mn, 0.008‑0.015% of P, 0.25‑0.45% of Cu, 0.40‑0.60% of Cr, 0.30‑0.50% of Ni, 0.02‑0.05% of Alt, 0.01‑0.05% of Nb, with the balance being iron and unavoidable impurities. The steel sheet can obtain excellent welding performance, and has ultra-high strength, high toughness and high weather resistance at a low P content by means of a reasonable ingredient proportion.
