The influence of alloy composition on the properties of steel

Carbon:

Exist in all of the steel, is one of the most important hardening elements. Help to increase the strength of the steel, steel has more than 5% of carbon, known as the high carbon steel.

Chromium:

Increase the wear resistance, hardness, corrosion resistance, is the most important owns more than 13% of the thought to be stainless steel. Despite the so called, if maintain undeserved, all steel will rust.

Manganese:

Important elements, helps to generate texture structure, increase the robustness, and strength, and wear resistance. In the process of heat treatment and roll pressure make steel internal DNA.

Molybdenum:

Carbonation agent, prevent steel brittle, maintain the strength of the steel in high temperature, appeared in a lot of steel, hardened steel air always molybdenum containing 1% or more, so that they can harden in the air.

Nickel:

Maintain strength, corrosion resistance, and toughness.

Silicon:

Help to enhance strength. As well as manganese, silicon in steel production process is used to maintain the strength of the steel.

Tungsten:

Increase abrasion resistance. Mix and the appropriate proportion of chrome or manganese tungsten used in the manufacture of high speed steel.

Vanadium:

Enhance the wear resistance and ductility. A kind of vanadium carbide used in the manufacture of stripe steel.
