The parking tooth with module 7.3 has a width of 13, This product is made of low carbon alloy steel. Generally, alloy steel is called alloy steel by adding other alloying elements in addition to iron and carbon. An iron carbon alloy formed by adding one or more alloying elements on the basis of ordinary carbon steel.

Influence on mechanical properties and Tempering Properties of steel The properties of steel depend on the respective properties of iron solid solution and carbide and their relative distribution. The influence of alloying elements on mechanical properties of steel is also related to this.

Alloying elements solidly dissolved in ferrite can enhance strength and hardness, but reduce toughness and plasticity at the same time. Among them, the solution strengthening effect of phosphorus and silicon is the most significant, and silicon has the most serious effect on toughness. A small amount of manganese, chromium or nickel can increase the toughness of ferrite.
