All industries today depend on steel and alloys. From large industries to small industries, they need to use alloy steels in their production. Industries such as automobile manufacturing, shipbuilding, air and space, petrochemical, etc., all of which are related to steel. Considering the different applications and variety of steels, choosing the desired steel requires knowledge of alloys and their compositions. 1.2080 grade steel, which is in the cold work steel family, has a different composition than 1.7701 spring steel. Low-alloy steels such as Ck45 steel and Mo40 steel are used in the construction industry, and as the alloys increase, the applications become different.
Automobile manufacturing is known as the largest industry in the world and a large part of the products in this industry are produced with alloy steels. As much as you are familiar with the automotive industry, you are familiar with the uses of steel in this industry. Global and Iranian car manufacturers need to improve the quality of their products. In the automotive industry, steel is used in many parts, 40% of which are used in the body structure, panels, doors, and trunk for high strength and energy absorption in case of an accident. 12% is in suspension and high strength steel strip is used.
Considering the sensitivity in the production of their cars, the world’s major car manufacturers buy steel with reputable brands and steel with desired alloys. The steels available in Iran due to the sanctions and the non-entry of steels made in the accredited factories are the steels made in India, China and Iran, and a limited number of steels from the accredited factories are available in Iran.
Construction is one of the important and active industries in all countries. Iron is usually used for construction. But in large and important projects, low alloy steels are used for greater strength. Ck45 steel is one of these steels whose price and properties have made it welcome in this industry.
