Today, let's continue to popularize the role
and function of various chemical components in steel.
4. W: The main function of tungsten in steel
is to increase tempering stability, red hardness,
thermal strength and wear resistance due to the formation of carbides.
Therefore, it is mainly used for high-speed steel,
tool steel such as hot forging die steel,
and wear-resistant steel.
5. V: Vanadium can refine grains in ordinary low carbon alloy steel,
improve the strength and yield ratio after normalizing
and low temperature characteristics,
and improve the welding performance of steel.
Vanadium in spring steel and bearing steel can improve the strength and yield ratio,
especially the proportional limit and elastic limit,
reduce the sensitivity of decarburization during heat treatment,
thereby improving the surface quality.
6. Ti: It is one of the strong ferrite forming elements.
Titanium improves ductility and toughness in low alloy steels.
The strength of the steel is increased as titanium fixes nitrogen
and sulfur and forms titanium carbide.
7. Nb: Niobium can refine the grains and reduce the
overheating sensitivity and temper brittleness of the steel,
and improve the strength, but the plasticity and toughness decrease.
8. Co: Cobalt is rare and precious,
and is mostly used in special steels and alloys,
such as heat-strength steels and magnetic materials.
