船体钢系指船体结构用钢材,主要有碳素和低合金船体钢两大类。本文拟就我国碳素船体钢的发展概况及牌号的沿革作一简单介绍。船舶建造规范对船体钢的要求是,具有足够的强度、良好的可焊性和足够的韧性。碳素船体钢不但能满足造船的三项质量要求,而且冶炼、轧制容易,成本低,所以使用广泛。 Hull steel refers to the steel structure of the hull, there are two major categories of carbon and low alloy hull steel. This article intends to make a brief introduction of the development of carbon steel hull in China and its evolution. The requirements of the shipbuilding code for hull steels are adequate strength, good weldability and adequate ductility. Carbon hull steel not only meet the three quality requirements of shipbuilding, and smelting, rolling easy, low cost, so widely used.
