Since ancient times,iron and steel,as one of the most important materials in industrial materials,have played an important role in the development of human society.In modern society,steels, in particular,are the main materials that are widely used in various industries,and they are also essential components that drive the progress of modern industrial production.
Iron and steel have many excellent properties and many advantages in industry.Firstly,it has high strength,which is the most outstanding feature of iron and steel materials.Most steels have high strength,especially some alloy steels with special chemical composition and heat treatment process,their strength can even exceed that of aluminum materials.Secondly,steel has good thermal and electrical conductivity,which can be used in many field.Thirdly,steel has good sealing performance and good wear resistance,which can reduce the production cost and improve the service life of the product.
In addition,the most important advantage of steel is its recyclable,which enable it to be used as a green material.Steel is the most recycled material in industry.At present,the recycling rate of steel exceedd 90%,which makes steel has become the favorite material for industry.Steel products are recycling after use,which can save energy and environmental pollution.Generally,the recycled steel products can be used again ,without changing the performance and productivity.
With the continuous development of technology,iron and steel materials can constantly create new alloys and new materials,such as stainless steel,high-speed tool steel,heat-resistant steel and so on,which has added more possibilities to the application of steels in industrial production. At the same time,new steel processing technologies,such as powder metallurgy technology,cold-drawing technology,welding technology and surface coating technology,have also been developed,which greatly improves the performance of steel.
At present,iron and steel have been widely used in a variety of industries,such as construction,agriculture,transportation,automotive,shipbuilding and so on.Steel is extremely important for modern production.In modern engineering construction,steel is mainly used for bridge engineering,building structure,conveying equipment and other fields,therefore it plays a very important role in modern engineering construction.In the field of shipbuilding, steels are mainly used for shipbuilding and sea platform.Steel can also be used as bearing structure in aerospace engineering.
For the industries such as electrical machinery,agriculture and forestry, steel is also very important.In the electrical machinery industry,steel is mainly used as electrical machinery shell,ventilation fan and instrument rack,etc.In the agricultural and forestry industry,steel is mainly used as tractor and harvester.All these materials show the position and contribution of steel in industrial materials.
In summary,iron and steel materials,as one of the most important materials in industrial materials,have innumerable excellent properties and advantages,which determined their important position and contribution in industrial materials.With the continuous development of technology,the variety and performance of iron and steel materials are constantly improving,which will bring more convenience to industrial production.
