Marajing Steel 

 
Strong ferrous alloys consisting of iron, nickel (about 17-19%), cobalt (8-12%), molybdenum (3-5%), titanium and aluminum are called marajing steel. This type of steel has a high toughness.

Characteristics of Marajing Steel

 
1.This type of steel has high strength and splor
2.Resistant to corrosion and cracking
3.It has weldability 
4.Are flexible
5. Resist wear

Marajing Steel Applications

 
Due to the unique properties of this type of steel, these steels are used in many industries, the most important of which are:

1.Making a variety of surgical instruments

2.Construction of fencing blades

3.Production of all kinds of bering rolls

4.Applicable in the production of hydraulic pipes

5.Production of various tools and molds

6.Use in aerospace industries

7.Composite Manufacturing 

6.It has machining properties

7.It has the ability to play

Methods of production of marajing steel

 
Marajing steels can be produced in general in the following ways:

1.Melting and casting
2.Aging
3.Forging and hot rolling
4.Homogenization
5.Ordinary Annealing

Aging Method

 
When producing maraijing steel by aging method, the strength and strength of the steel increases dramatically and then decreases. This decrease in strength and strength is due to the formation of iron carbide (austenite) and the coarseness of sediments. 

Corrosion resistance in marajing steel

 
As mentioned earlier, marajing steels have high corrosion resistance so that this resistance is about 1240 to 1720 MPa. This resistance has been measured by researchers in seawater because seawater is rich in corrosive substances. 

Research has shown that this type of steel can withstand between 2 and 3 days in the face of corrosive materials and does not break, but microstructural research of this type of steel indicates that in the conditions of continuous confrontation of marajing steels with corrosive substances after 6 months, cracking.
