Structural alloy steels are those types of alloy steels that are used to make certain materials or parts. Alloy steel has different chemical, physical and mechanical quality parameters depending on the additives that are included in its composition. These metal additions are called alloying elements. Most often, impurities of manganese, chromium, nickel, copper, vanadium, cobalt and other metals are added to alloy steel. An example of alloyed steel is 38KhN3MFA with an admixture of chromium, nickel, vanadium and molybdenum.
Structural Steel Types and Applications
Alloy steel can be low, medium and high alloy, it depends on the percentage of alloying metals included in the alloy. As a metal complement, one metal can be used, or several. Each steel with alloying elements has its own grade, where the amount of carbon is indicated by the first two digits, and the numbers following the lettering indicate the amount of alloying metal.
Features of chromium-nickel-molybdenum-vanadium steel
This variety has increased resistance to high temperatures, and can also withstand strong mechanical stress due to the admixture of vanadium and nickel. This steel grade is not used for welding. Mainly used for the production of parts subject to high temperatures and high mechanical stress.
