EH32 steel marine common
1, the general hull structural steel A, B, D, E stage is based on the temperature of steel to distinguish between the impact, the impact value of each steel grade are the same, not according to the intensity level of distinction.
A grade of steel is at room temperature (20 ) force of the impact.
B grade steel is at 0 force of the impact.
D grade steel is at -20 force of the impact.
E grade steel is at -40 under force of the impact.
High-strength hull structural steels can be divided into AH32 DH32 EH32 AH36 DH36 EH36
2, high-strength hull structural steel preheat requirements: Any AH, DH, EH 30mm thickness is greater than the angle of the joints, preheat to 120 ~ 150 .
3, thickness ≤ 30mm, the ambient temperature below 5 , preheated to 75 ; the ambient temperature is below 0 , preheated to 75 ~ 100 .
3, TMCP steel (made in Japan), from time to warm up before welding.
Carbon (C) ≤ 0.18
Manganese (Mn) 0.90 ~ 1.60
Aluminum (Al) ≥ 0.015
Silicon (Si) 0.10 ~ 0.50
Phosphorus (P) ≤ 0.04
Sulfur (S) ≤ 0.04

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.
