Corrosion resistant steel is defined as copper, nickel and other corrosion-resistant elements added in carbon steel with the total amount of alloy elements less than 3%. Different kinds and contents of alloying elements play different roles. Is DH32 steel corrosion resistant? Let us check DH32 steel chemical composition first.
DH32 steel chemical composition:
| C | Si | Mn | P | S | Als | Nb | V | Ti | Cu | Cr | Ni | Mo |
| 0.18 | 0.5 | 0.90-1.60 | 0.035 | 0.035 | 0.015 | 0.02-0.05 | 0.05-0.10 | 0.02 | 0.35 | 0.2 | 0.4 | 0.08 |
DH32 steel is hull structure steel, which is also called ship steel. The working environment of ships is harsh, and the hull is subject to seawater's chemical corrosion, electrochemical corrosion, marine organisms, and microorganisms. So of course, DH32 steel is corrosion resistant.
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.
