2021 High quality Hot Dip Galvanized Coil - Ship steel plate price A36 Q345 carbon steel Plate for ship building – Lu

Introduction

Shipboard steel plates refer to hot-rolled steel plates produced in accordance with the requirements of the classification society construction rules for the manufacture of hull structures. Due to the harsh working environment of the ship, the hull is affected by seawater chemical corrosion, electrochemical corrosion, marine organisms and microbial corrosion: the hull bears the impact of strong wind and waves and alternate loads: the shape of the ship makes its processing method complicated, so the steel of the hull structure The requirements are very strict. High strength, good corrosion resistance, welding performance, processing and forming performance, and surface quality are required. In order to ensure quality and ensure sufficient toughness, the chemical composition of Mn/C is required to be above 2.5, and the carbon equivalent is also strictly required, and it is produced by a steel plant approved by the ship inspection department. According to the lowest output point of hull structural steel, the strength grade is divided into general strength structural steel and high strength structural steel.
