目前,世界各国大型民用船舶的船体钢可按强度分为两大类,即普通强度船体结构钢和高强度船体结构钢。普通强度船体结构钢是指抗拉强度为41～50 kgf/mm~2[40～49 kPa]的船体钢,高强度船体结构钢的抗拉强度为51～63 kgf/mm~2[50～61.8 kPa]。本文仅对高强度钢在造船工业中的应用及其发展情况作一简单介绍。
Currently, the hull steels of large-scale civilian ships in various countries of the world can be divided into two categories according to the strength, namely normal-strength hull structural steel and high-strength hull structural steel. Ordinary strength hull structural steel refers to hull steel with tensile strength of 41-50 kgf / mm2 [40-49 kPa]. The tensile strength of high strength hull structural steel is 51-63 kgf / mm2 [50 ~ 61.8 kPa]. This article only for high-strength steel in the shipbuilding industry and its development of a brief introduction.
