The Use of Carbon Steel Slab in the Construction of the Titanic

Carbon steel slab or carbon steel is steel in which the carbon alloy is in the range of 0. 12-2. is 0%.

Carbon steel has no other elements except carbon and some common elements (such as silicon, manganese, sulfur and phosphorus).

By adding some elements to iron, alloys are made that have excellent properties.

For example, by adding chromium to iron, stainless steel is made, which is highly resistant to various corrosions.

Steel is stainless when it has at least 10.5% chromium.


After combining with air oxygen, chromium forms chromium oxide, which forms a zinc layer on stainless steel.

This layer is not visible, but it makes the connection between air and metal disappear and the steel remains healthy.

A higher amount of chromium and some other elements in the alloy such as nickel and molybdenum strengthens this layer and increases the property of being rustproof.

In carbon steel, there is no other element except carbon and some common elements (such as silicon, manganese, sulfur and phosphorus).
Carbon steel is a type of steel whose maximum weight percentage of carbon is 2.1%. According to the definition of the American Iron and Steel Institute, AISI, steel is called carbon steel when:

No minimum value has been specified for the elements chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium.
The specified minimum amount of copper should not be more than 0.4% by mass.
or the maximum mass percentage of the mentioned elements does not exceed these values: manganese 1.65%, silicon 0.6%, copper 0.6%.

The term “carbon steel” may be used to distinguish it from “stainless steel”; In this case, carbon steel can also include alloy steels.

By increasing the percentage of carbon in steels, the possibility of hardening and increasing its strength also increases through heat treatment, but on the other hand, this work reduces its ductility.
