Abstract:
Product designs and properties of 6 steel products for shipbuilding are described. They are new TMCP(thermo-mechanical control process) steel plates, weldable
with high heat input, for container ships and LP(longitudinal profile) plates, both contribute to the increase in productivity at shipyards through the large reduction of welding time, anti-corrosion steel plates for crude oil tankers NAC5 which contribute to high performance of ships from the viewpoint of corrosion, cladded
steel plates for chemical tankers, anti-corrosion pipes,JFE-MARINE-COP, used in crude oil tankers for loading and unloading crude oil, and shapes for shipbuilding
which are produced using TMCP to realize weldability as good as steel plates.
Introduction
In recent years, the shipbuilding industry has energetically promoted high performance of ships and improved productivity in construction in response to vessel diversification(trend toward exclusive-use ships). In the process,the industry has also pointed out a variety of developmental needs related to steel products, resulting in the creation of new technologies and new products.This report describes the product design concepts and properties of the following 6 products which were developed by JFE Steel in response to these needs. In the field of plate, they include new TMCP (thermo-mechanicalcontrol process) steel plates for high heat input welding
for container ships, which contribute to improved productivity by greatly reducing welding working time, and LP steel plates (longitudinallyprofiled plates, also called taper plates), new anti-corrosion steel plates for crude oil tankers, NAC5, which contribute to higher performance in ships through improved corrosion resistance,and clad steel plates for chemical tankers. Tubular products include JFE-MARINE-COP for crude oil tankers,which improves corrosion wear performance in onboard oil receiving pipes used in loading and unloading crude oil. Among shape steels, JFE Steel has developed TMCP technologies for shapes for shipbuilding which provide weldability equal to that of plates.

GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
Bulb flat steel for shipbuilding
The bulb flat steel is a kind of medium section material which is mainly used in the field of shipbuilding and bridge building, and the shipbuilding bulb flat steel is an auxiliary medium section material for shipbuilding.
